I am debating between CAT, Makita, and Ridgid. Ridgid has 3 years warranty.
Thank you for this very helpful video. I have this same compressor and it is bleeding out a lot of air from the unloader the entire time the unit is pressurizing. Consequently, it's taking a lot longer than necessary to fill the tank. I'm going to do the solenoid mod but can't seem to figure out how to remove the unloader with the elbow as shown at the 1:00 mark in the video. Any suggestions on how to remove? Conversely, I presume I can just remove the hose from the unloader and insert it into the solenoid and leave the elbow unused behind the pressure switch?
that noise must be coming from the two big bearings that hold the spindle spline-drive and most likely due to how the v-belt pulley is attached to this part of the construct. I guess it would be better to have the belt attach to that spline drive WITHIN the housing, by turning away the upper gear and replacing it with a pulley.
The way you mentioned all the sources of your inspiration really speaks for your approach!
You talked about everything but the spindle encoder wiring and the vfd
still works well! thanks
This is incredibly amazing! You inspired me.
Hello I’m from Brazil im using the hbs57 driver that looks pretty much like yours… I added a clock to the x axis to see if it was going ok but seem it’s not going exactly as should. I’m using fluidnc as controller with an esp32 board to send the commands and it don’t seem to be stable in advancing for example. It seem to me like the driver may be the problem could you give me some advice?
Can it cut 12 MM - 20 MM MS Iron Rod?
Hello, did you use now the same gearsize on the encoder and dthe spindle size or a different size.Did you figured out how to manage this in linuxcnc. My problem is, that i do not find a gear for the encoder what is as big as i need for the spindle size
Yes, I use 1:1 gear ratio. You'll be able to make the needed spindle gear your CNC router. The number of pulses needed per revolution needed by LinuxCNC is small, so gear accuracy is forgivable.
i use my linuxcnc small mini keyboard wireless usb keyboard, not perfect but working well move spindle. i not understand code any and not can build good pendant to my liuxcnc but want make and use. but need step by step manual how made. encoder and move buttons, touch plate and more but not understand any i has try make not working, lot only errors in linuxcnc display.
Great your video lathe's, 😊👏👏👏 @arduinomaquinas thank you man 😊👍 subscribed !
Hi. Going through all the comments as well as all the documentation. So I also ended up with the version where the 7 segment display is also working so I could ensure all is working correctly. The problem is that I cannot get the Nextion display to work. So I am now open for a couple of next steps. If you or anybody still have a compiled version that was done with the old CWARE and where the screen was working I would really appreciate if this can be shared as I do not see it in the GitHub files. I have now in the meantime ported the code and everything else to the latest libraries but the problem stays the same. 7segment and servo is working but Nextion does not work. Any help for a compiled working .out file would be appreciated for my troubleshooting process.
Are you using Python with Scikit-Learn library for the machine learning? And Python + Flask for the web application? It's an amazing video, great job!
is there a way to get the 1 pixel array sensor? I would love to build my own spectrometer
kent hello and thanks for the video im wondering can i get the plans or buy the drawbar from you
Kent, thank you so much for posting this. Was convinced I had an encoder problem until I soldered the motor connectors. Fixed the problem immediately. Btw, my connectors had no melting/damage, just a shoddy connection.
Hello Kent, your work is impressive and keeps people like me motivated to move from Mach4 to Linux CNC faster. Keep it going.
Have you tried A dual VFD drive motor? High torque at low rpm.
Hi Kent, are the models for your mounts available anywhere. Understand if they are not. Great work :)
Hi Barry, please check if the f3z and step files at the following address will help you. If not, send me an email and I'll send you the entire mill head model. github.com/kentavv/kvvcreates/tree/master/pm25mv%20cnc%20mill
If you were to do this today, where would you suggest one to buy a kit. Specifically I have a Sb 10K
I'd buy a turnkey CNC lathe and keep the manual lathe manual; they are not substitutes. Kits are great if seeking the DIY CNC experience. A DIY CNC from scratch, unless for research/education, only makes sense for something that can't be bought. It all takes time and that time could go into project enabled by the CNC.
were di we find the code to weight pitch to an Arduino ? as i cant get the board you spiking of. les England
wow, as a photographer, and machinist, this is very impressive imagery, I was completely lost in the explanation, except for the 50mm Schneider lens.....you have some great Manfroto C-Stands and Grip gear.....and of course your South Bend lathe......best wishes from an old guy in Florida, Paul
Hey! Ive been recently working through my first CNC conversion on a mini mill. Trying to use effectively the same set up as this but with all 3 axes... Im up to like week 3 or 4 of trying to get the handwheels going. Is there an appropriate way of getting in touch with help for the hal side of things... (i think thats where the problem is
Hi Nick, you could check against my configuration github.com/kentavv/kvvcreates/tree/master/linuxcnc/configs/sb1001_lathe/mesa and write to me at kent.vandervelden@gmail.com
Where could I buy the Leadshine servo motor? I think the ones you have are 2N.m, everyone recommends 4N.m for the X/Y-axis and 9-12N.m for Z-axis. Is 2N.m enough? Thanks
In the US, I purchased from www.americanmotiontech.com/ Measure required torque at the ballscrew with a torque wrench - not much is needed, break away and moving. I've had no trouble with 2Nm, and demonstrated reserved capacity by adding weight to the head while monitoring follow error. If not able to measure these, one would be conservative and increase the motor size, especially if using open loop motors. For these small mills, we should be working at lower force levels. Smaller faster cutters and less force. Thank you for asking. Happy holidays!
@@kentvandervelden Thanks for the reply. This makes sense. Happy holidays!
8:48 When you run very small diameter tools the runout matters more and the "flex-force" is lower.
Absolutely! Thank you
In general what would say the final repeatability tolerance is like?
For this class of machine, repeatability is swamped by a multitude of other sources of error. From experience, not exhaustive direct testing, for a CAM generated tool path, I expect accuracy within 2thou within a 6" cube. Manual programming improves this. Like everything, improvements sends costs up quickly. Hope this helps. Happy holidays!
@@kentvandervelden Thanks for the reply. Happy holidays.
Can two of these be run simultaneously into a common hose? Do I just need check valves between them? They don't seem to like to start if there's any back pressure they have to work against.
The compressor with a higher on-setpoint would run more, and the second would only turn on if the pressure continued to fall. The larger CAT models have multiple compressors, and a common pressure switch. Once the compressor turns off, the cylinder is unloaded. If the unloading does not complete, before the compressor turns back on, the motor will stall, overheat, etc. The unloading necessitates a check valve between the compressor and the tank. No additional check valve should be needed. Interesting situation you describe. Depending on need, may also consider a nearby large receiver tank instead of multiple compressors. Happy holidays!
@kentvandervelden thanks for the reply. Having a big tank makes the system take forever to get up to pressure. The large tank solves short term needs of high cfm, but doesn't solve a longer term need such as spraying.
What a unique combination of skills Metal work FPGA CNC to name a few. That's impressive
I appreciate your message a lot, thank you.
Thanks
everyone shows how to mount the encoder but no one shows how they wired it up to the control board.

great video very informative, i have the exact same tool setter for the price i think it outperforms its real world monetary value, +1 subscriber
Great job,Thanks!
Nice but I question the lack of rotation on the tool post. I have a rigid tool block as well but I'm changing the angle of the block all the time for chamfers, reaching into holes, ect. Having my tool post stuck at 90 degrees would drive me crazy.
I agree, otherwise it looks great!
I thoroughly enjoyed your presentation of sources of movement and solutions to mitigate it and bring solidness to cutting. Thank you!
Just curious, how do you turn tapers? Or do you just switch back?
CNC interpolation of the X,Z axes. The tool can be tilted a few degrees in the tool holder. I've not switched back to the compound. Hope this helps. Thank you
Can you share the 3D Printable assets?
THANK YOU! Super helpful!
You can prevent switch bounce problems by using a normally closed switch

I dont know did you already know that but, I need to say that. You can use build-in breaks to stop motor way faster and that can reduce your change in direction time.
Try milling the hex with conventional milling rather than climb milling. You probably won't get that "jump". I believe the cutter is digging in when you do that radius.
Did you ever get it straightened out? Did you need a 1:1 pully to match the one on the lathe spindle?
Yes, with 1:1 pulley everything worked well. Thanks
I have closed loop stepper and my x axis is always failing at the same location every time I run the machine. I can’t tell if it’s a binding issue or a cabling issue such as what you described in your diagnostic search. Do you have any suggestions as to how to check the driver for fault that could be causing the problem. I will double check the mechanical side to see If there is a problem that I may have missed.
I used the mesa thcad 2 A/D converter, a touchplate , g38 commands, and the ohmic.comp in linuxcnc to read frequency put out by the mesa card when 24v is going through the circuit so one lead goes to the cutter that has 24v on it and one lead goes to the touchplate from the mesa as the tool gets closer to the touch plate the frequency starts to go up the closer the 2 leads get, I set a threshold for when it reaches a full 24v and the g38 commands do the rest I think this method gives you the most accurate way to set tool heights would you be able to run some tests to find out Im applying a component from QtPlasmaC torch height control dubbed hypersensing its using ohmic sensing and software instead of relays to trigger the surface contact g38.3 probes to the piece and g38.5 slowly moves away from the surface and the moment contact is lost that's the height I think its more accurate because it removes the time a relay takes to trigger I could be wrong I can send you the custom hal file i used if your interested
Did you connect the yellow wire to resistors?what type of resistor did you use?I'm using 2.4k ohm resistors and its not working,,help me
Attaching the probe that I received to a Mesa 7i76e didn't require an external resistor at 24V. The diagram in the instructions show a resistor in probe. If your multimeter uses a voltage greater than the Vf of the LED, you can measure if the probe has a resistor by measuring resistance across the probe light leads. If meter reads zero ohms, try flipping the leads. If reads zero ohms both directions then meter probably uses too low of a voltage to get the LED to conduct.
Can confirm, I have this same model and my couplers both leaked from the factory lol
I have this same model compressor and wanted to change the couplers, but I can't get them to budge. I can see what looks like adhesive on the threads. Were yours difficult to remove?
Might need a little heat to break the thread lock.
@@kentvandervelden Thanks. I'll give it a try.
Great, Would mind if I ask, I have interest to know the part number of the CCD in that device. I have been trying to make choice on CCD sensor for a project. This may be a good start point.
