Jason I have always like your RC videos. Now I subbed here. I have a VERY modified Syil X4. Just learning at 52 and loving it. I'm pleased you have got into this and been successful. I actually watched a video of yours about a year ago and it partly inspired me to get into it myself. I have always been interested and now I'm obsessed. My down fall is I need to keep designing through the week so when the weekend comes I have something to machine. For the most part the machining is the fast part of the process. Just finishing up a design for a pretty complex pump for an RC project I have in mind and look forward cutting on that latter today.
If you take the right end block and jog the X the same direction as your zero to the the end of the gauge block stack. That would minimize any backlash and indicator error. and give you the true machine error.
I like the quick check, but I would do and indicator sweep to eliminate the error from the Haimer. Much harder to show on camera, so I don’t blame you for not doing it.
.0006 after reversing, ok. But "over 9 inches" has little to do with backlash. It might be screw inaccuracy. Play in the nut-screw interface, and play in the ball screw support bearings is not particularly position dependent. Am I wrong? And by the way. This is why you always bore, and not interpolate, cavities meant to hold accurate bearings.
I once measured a really nice machine backlash by hand jogging back and forth and got about 4 tenths in x and y. I was alarmed at first, but then I wrote a program that jogs x-, lets you zero out the indicator, then jogs z+ over the measured surface, x-, x+ and then z- back to the block, and got the expected result of within the indicator accuracy. I suppose the machine must somehow loosen up the requirements when manually jogging, not sure why, but I'd be interested in seeing if you also get a different result when measuring this way.
Really exciting timing for this video. I just got a Brother TC-225. Checking this older machiene is going to be good because there isn't much documentation on these that I've found. Anybody know more about Brother cnc-400 pre speedio era machienes they make today.
Just a small note on your tests that you have to keep in mind, very rarely is the encoder on the handwheel as accurate as on the axis motor. These tests you are doing is ok for a rough indication, you should really program these moves with your MDI commands to see the true axis movements. Nice looking machine though.
Not true. The control is looking for a specific signal from the mpg. It either sees it or it doesn't. The axis will either move the correct distance or it will not move at all.
@@danarrington2224 I would suggest that you do some research. I am in the CNC world (Application Engineer)since the 1980’s and can I tell you that working on various CNC’s that you only have to do the test for yourself to see the result.
@@christom5832 When you are moving an axis with the mpg each "click" of the handwheel sends a pulse to the control. The control in turn will move that axis by a set amount. As long as you are spinning the wheel slowly, like he is doing in this video, the accuracy of the movement will remain true. You should also know that most controls have multiple parameters for setting backlash. One for manual movements and one for programmed movements. Your initial comment is therefore inaccurate.
@@danarrington2224 As I said in my first post, the handwheel is not as accurate as you would like to think on different machines, more high end the more accurate. When we do laser mapping we use the motor encoders and programming and not the handwheel because the handwheels are not as accurate as motor encoders.

Awesome development Jay! Finally some Syil X7 videos that will have some great content. Can hardly wait. Ciao, Marco.
Very promising start to the series!
Looking forward to this new series, even more so now, because I own a Syil X7-20, mine has Siemens control.
Getting our Syil X7 in sometime this week! Glad you're walking through all this.
Can you share which spindle and controller you chose?
@@qcnck2776 For sure, we got the 12k RPM spindle and the Syntec 22MA. It was a standard package machine that was already on its way.
@@kyleflorek7074 Thanks!
Awesome, super excited for this new series. I love the Syil X7!
If you take the right end block and jog the X the same direction as your zero to the the end of the gauge block stack. That would minimize any backlash and indicator error. and give you the true machine error.
I know Peter. But I didn’t do that at the first point. I was just simulating a commanded move.
Exactly. Without eliminating the backlash error it's a useless test.
Very nice!

Awesome! Thanks for doing this!
Do we really need to teach people how to crash a CNC?
Well. Technically I own CNCFundamentals.com as well.
looking forward to this thank you....
Takes a lot of Dedotated Wam to make things happen.
Seriously tho, this is a good start, kick it!
rock on man!!
interesting machine
I had a Bridgeport with linear rails from 1996 that I paid $3500 for. Backlash on XY and Z was no more than 0.00015"
TC22? I got one for $1500 that I can't even measure backlash on with a .0001" indicator. Getting a Linuxcnc retrofit now.

that's awesome ❤️

Great video. Looking forward to the series. I'd love to know what a machine like that goes for?

Why would you think that this machine has back lash the scale measures movement not rotation of the lead screw so there is no need to check ???
Probably because it doesn't have scales.
0.01524mm (0.0006in) is good? Guess I'm expecting too much from my upgraded 6040 :)
I wish you would tell me which machine to buy! I am comparing HAAS Mini, Tormach 1100MX and this X7.
Where is the link to the gaugeblocks, nogo base and indicator? :(
Noted. I’ll get
Those in there today.
Did that machine come with a Ballbar report?
was that a tormach in the back?

you dont have to enable ads on your channel though
Hello, m'y X7 has been ordered about a month ago, waiting for the siemens 808D/A. Does the siemens have Backlash compensation?
I dont know much about the siemens other than its a great control
Key words here - "I don't know much"

Great input....when i get some time we can try this with a bunch of postive and negative G91 X.001 moves.
Thanks,

Cool machine but hard to justify the cost of it in comparison to Haas or other vendors on the used market.
True and has will be releasing the tm-0 which will be cheaper than tm1
how much does this machine goes for?
Starts around 30 000 usd
@@markuschampos5750 hmm but u can get a HAAS TM1P at about those money...
@@seriousCADninja Ok, then go for it.
Tmp1 60,000@@seriousCADninja
