You make it sound good. Problem, it is not full CNC as you said. Perhaps I missed something, however as others have said there is no way in this kit to coordinate spindle rotation with X Axis for threading. At the end of the video it appears that thread cutting on this Lathe has been disabled.
you need an encoder on spindle motor for CNC threading. in this video CNC system controls feed but cant control spindle RPM, so threading is posible but can't be precise. (sorry for my english)
Not to worry. Flashcut Control Systems are of an "Universal Fit" design. Thus, even backlash measuring beyond the entire universe, is universally controlled. However, you may need to go fix a sandwich or something, while Flashcut takes up the slack.
Dimitrios Savoulidis Particularly on a lathe, it's a fairly easy matter to use a split Delrin nut over the exposed Acme lead screw, heat the screw with a heat gun, and use a C clamp to compress the Delrin nut halves once the Delrin begins to melt. This is a cheap and easy way to make a zero backlash lead screw nut that's molded to your lead screw. The friction is higher than it would be with ball screws but these steppers should not be losing any steps, and if you have a Grizzly G0602 lathe, you probably aren't in a big hurry when turning your parts, anyway.
Simply place the slack measurement on each axis in the software, and each inverse movement will consider that slack. Just as a human operator would do.
@@RafaelCantarella Really? How is it going to compensate for backlash during full 2-axis turning? If the X-axis leadscrew reverses rotation, there will be a serious defect in the work piece. Moreover, there will be more backlash in the region of the leadscrew where the most work has been done.
I’ve tried to get ahold of you guys for a price on a retro kit for a Bridgeport mill series 1 to no eval ! I’ve called 5 times and sent numerous emails. I tell you what I won’t buy from you guys because what if I need help?
hmmm just read that its priced around 4000 dollar , for that amount of money you couldve machined some way better mountings ans atachments for the steppermotors (i have bought all the parts for a cnc conversion and the price for those parts includung the computer arent all that high , and i got the achorn driverboard ), it should work but its incredibly builky and looking like a kid trown it together with a drillpress and a hacksaw, for the cros slide use an extended leadscrew , mount the stepper motor on the back of the crosslide leadscrew extention and keep the original crank in the front , might even be able to make a simple disconnect sleeve to connect the steppermotor for the sled drive you could remove all the gears and mount the steppermotor on either end of the leadscrew , think if you take the leadscrew out and turn it around you can atach the drive for the steppermotor on the machined end for the gears that are now on the tailstock end , again you can use a disconnect sleeve or dissengage the drive at the sled and still be able to use the lathe manually other things im missing here are the rotary encoder that you need to make single point treads using cnc and limitswitches so the lathe can set itself up for zero after the steppermotors are reconected
Hello sir , what type of stepper motor have you used and also of how much volt and torque. i would also like to know about drivers and power supply. And can I use mac3-5axis interface board for using 4 motors ?
I'd just like to have that lathe as an upgrade.. It does not have a digital speed indicator thought. No manual override in the system and guess I would spend more time trying to program every little part. Forget it The new faceplate just removes all the useless gear and speed scales.
My question is how do you thread cut? I didn't see a installation of an encoder for the headstock. That's my hold up on doing a CNC conversion my Sheldon. Finding a encoder for the head stock to track RPM and position for threading. The #1 reason for me to CNC my lathe is for metric and SAE threads. I can do SAE now, and if I set things up right on my taper adapter I can do pipe threads as well. I don't have a gear to do metric threads.
RobiSydney the encoder is very easy. Mach3 only supports one pulse per rev. I used an optical switch {like that found in the "hook" of a telephone} i mounted a washer with a 1/2" notch to my machine spindle {sherline 4000}. Thats all you need. You can use a positive or a negative space to create the interruption, doesn't matter as the software will accept either a high or low trigger.
+RobiSydney I used a rotary encoder (1440 pulses per rev) on my home made Myford cnc conversion. I only use the Z pulse to start the threading. After that the leadscrew steps are calculated from the encoder pulses. Hand rotation using a spindle crank, or a VFD and motor (which I have installed) both work
Hi, I don't think I would allow that retrofit on my lathe. There doesn't seem to have been any thought given to the modifications,the lead screw drive motor should have been fitted inside the gearbox housing as a direct drive, the motors are powerful enough to drive direct. The top slide motor mounted vertical with spur gears or twisted belt drive. All in all a poor example of thinking problems through. PFGHW
Gre za NEMA23 koračne motorje, ki se dobijo relativno ugodno. Celoten set, dva motorja, napajalna enota in pa dve končni stopnji, se dobita za manj kot 200eur. Potrebuješ še računalnik ki deluje kot krmilnik, s primerno programsko opremo. Zelo zaželjen je tudi ločen usb kontroler. Če potrebuješ še kakšne informacije, me kontaktiraj.
@@someotherdude But it just makes no sense to buy upgrades 5 times the price of the machine. Just buy an Emco CNC for that money. Funny how he mentioned the brands that it fits on at the start, couse it are all the same machines with different colours. xD
I can see 2 cords Plugged into the electrical outlet behind the lathe, Don't even tell me that you are Disassembling and retrofitting this lathe with the POWER CONNECTED. You just pulled switches,controls and the GROUND. Am I the only one concerned here? ,
the adapter piece for the X-stepper motor..... Oy. That is begging for a redesign. As in much more sleek and slender, so you can see and reach right past it. You don't need extreme rigidity there. That huge, blocky thing has to go!
Тези машини са с такава възможност и са проектирани също от можещи и знаещи хора ако искаш електронна машина си купуваш електронен струг според мен не е нужно да реновира струга
you just trash the lathe, with out spindle feed back, and you removed manual control I can't think of what uses it would be. I guess that you could use it for a wood lathe at this point.... you have no spindle speed control or on and off. there is no way I could make threads at this point.....and to just make a simple part it would take hours of CAD and setup time! Sorry I don't under stand you took a useful tool and made it a nightmare .... Besides the load of the belt tension will destroy the x axis nut in short time it is not built for that side load!.................
40 Years of manual, nc and cnc engineering and Repair I fine that without spindle feedback there is no way for the kit as shown could cut threads thus making it computer controlled incomplete and without much functionality . I want to thank you for your quick and on the spot comment it is always appreciated.
Barely any of us do this, this man wore that phrase out in this video. It would be a chore to be around him in person It aggravates me when people repeat the same phrase over and over.
What a stupid design! You really missed all opportunities to make it useful. Why all this stuff in front of the X-axis? Can’t you mount the motor on the back side directly? For what purpose is the belt? That happens when people have no knowledge but unfortunately can make YT videos. And this Z-axis motor mount is an awful design, too. If this is the way to make America great again, then it‘s still a long way to go… in the other direction 😛😁
Stunned, this kit is $4000 and doesn't include ballscrews or a spindle encoder.
Did I miss something? Why was the panel with the switches removed? Nothing was changed except for changing the original with a blank one.
@Terrell Reese Nothing remotely to do with the video 😒
You make it sound good. Problem, it is not full CNC as you said. Perhaps I missed something, however as others have said there is no way in this kit to coordinate spindle rotation with X Axis for threading. At the end of the video it appears that thread cutting on this Lathe has been disabled.
That's what i was going to ask. i thought maybe there was going to be a spindle position sensor or something.
He did say an encoder was available for upgrade.
U make only for benchtop lathes and not heavy duty lathes ?
so, you disconnect the leadscrew from the spindle motor.
how you gonna cut your threads now ?
Threading command ?
you need an encoder on spindle motor for CNC threading.
in this video CNC system controls feed but cant control spindle RPM, so threading is posible but can't be precise.
(sorry for my english)
vasyapupken
You can get away with a simple optical switch and a dog on the spindle. 1 tick per revolution, no live tooling but it's enough to thread.
Cool mate thanks for sharing

The backlash of this Chinese lathe is biger than the universe. You have to use ballscrews.
Not to worry. Flashcut Control Systems are of an "Universal Fit" design. Thus, even backlash measuring beyond the entire universe, is universally controlled.

Isn't it fairly easy to account for any backlash in software?
When do I unplug my lathe, before or after I start working on it? So no ball screws?
They honestly aren't necessary! Why does everyone suddenly think a hobby lathe has to make mil-spec parts?
What about the drive gears are they no longer needed.
I keep my initial question:
To avoid backlash, shouldn't you replace the original leadscrew with a ball lead screw?
you can set a software bachlash compensation... most controllers allow such configuration
Did you put a sensor on the spindle shaft?
how can it thread if the program doesn't read the rotation of the shaft?
Thank you
Hallo sir. It is available in india
This kit is a joke I can't imagine how you're going to deal with the backlash in those cheap screws.
Simply place the slack measurement on each axis in the software, and each inverse movement will consider that slack. Just as a human operator would do.
@@RafaelCantarella It's backlash compensation...
@@chrisreinhardt5136 Yep !
I don't think so, you can put backlash compensation into your control software. A hobby guy can get very satisfactory parts from this setup.

motor does not know the limit of the axises (no feedback to the driver of motor to stop the stepping when reach the end of the axises) but nice work
Nice!
Which stepper motor is it?
Hello sir ,
what type of stepper motor have you used and also of how much volt and torque. i would also like to know about drivers and power supply. And can I use mac3-5axis interface board for using 4 motors ?
I have used less motors on one of those cheap Chinese breakout boards than what its built for and found that it causes interference.
Hi, what power is servo motors ?
Who can provide the hardware for this modification?
What is price this lathe i want one
what about the back lash is there any?
mike stetson all the stock backlash remains.
Are you still monitoring this UA-cam video?
Hello ? Hello ?
do you have the printer convertion kit

how to change speed or how the speed controlled it is has a knob?
