China NEMA 34 motor kit problems

[CNCMAN172]

Trell,
You might want to use a standard ethernet cable, most newer cards can work and determine where transit and receive are automatically. I had several cross over cable that were actually missing several wires, I could not understand why they were not working correctly and I buzzed them out and low and behold several ways were not actually used in the cable. I got a standard ethernet cable that I tested on my home computer and pulled that in and all worked as expected. Just a thought.

I use it mine with an standard cable , in a router , and it see it.
There is an app who see if u connect tha uc300 eth , use that and config the ip of uc300eth with ur system

[Trell]

Got the UC300ETH from CNC4PC.com with there C10 break outboard and got everything running with 150 IMP with no issues but one.
I am using ger21 screen set 2010 for tool touch off. I get the "Probe Active" light to come on when touching the tool in the router but it will not stop the the Z axis. Anyone got a ideal about this one.
Feels good to get the CNC running again. Don't think I will ever build another cnc without a UC300ETH.

What version of Mach3?
What version of UC300ETH plugin?

Are you running the 2010 macros?
Is there any message displayed on the screen?

I can install Mach3 on my laptop and go test this with my UC300ETH and see if I can duplicate it.

[Trell]

Ver R3.043.066 for mach3
V1.006 for UC300ETH
On starting Mach3 I do get some errors messages about DLL defective. Reload. Then UC100 V2_148.dll defective plug-in found ignoring.
Uc300 V1_054.dll defective plug-in found ignoring.
UC300 V1_056.dll. Defective plug-in found ignoring
After hitting OK on the errors Mach3 will open and work.

Try changing Mach3 to 3.043.062
You can download it from the FTP site:
ftp://anonymous:guest@ftp.machsupport.com/

Also, go into your Mach3\plugins folders and delete thos other plugins that are causing the error messages. You should only have the UC300ETH plugin in there.

[ger21]

Try this plugin.

[Trell]

Got all the opening errors fixed. Thanks for that fix.
Downloaded the Mach3 software and installed. Still will not stop the Z axis

Try the new plugin I just posted.
Make sure you delete the old one.

[Trell]

ger21, the wizard of the CNC.... looks like that fixed it right up.
The Z axis downward movement on the first touch is as fast as it was but the 2nd downward movement is super slow like may .01 IMP. Is there a way I can make the 2nd movement a little faster?

[Trell]

Never mind it works fine TY for all the help

CNC running at 150 IPM wow it os so smooth compared to just a breakout board. Thanks for ever ones help.

Well, it is running a lot better, but having a issue with running a gcode
When running a table leveling g code the CNC will stall but just sometimes. Driving me crazy. It will happen on the x axis most of the time but in different places.
I have already checked the obvious problems and everything is free
Anyone have any ideas??

If the cnc stalls then is aproblem with speed of stepers , what is voltage u use for driver ?
The motors i think have low internal resistance , and they need high voltage in order to achive a high rpm .

[Trell]

Yes you are right. The stepper motors do need high voltage for speed but the CNC will stall at 80 IPM or at 130 IPM. I will try 50 I PM and see if that helps

Try a higher microstep setting. It may be a resonance issue.

[Trell]

Ok got the step on the drive set to 10k and the step per inch set to 51055.369. Seems crazy but I have run two table level passes with no missed steps. Will do more testing tomorrow https://uploads.tapatalk-cdn.com/201...db02399418.jpg
Hoping it keeps working

Seems like the CNC has stopped missing steps but nut got another issue.
When running a square with gcode the cnc will round three of the four corners. When I run a sim in Vcrave everything looks fine and square but does not cut that way. Any one know what causes that. https://uploads.tapatalk-cdn.com/201...96a50c9fa6.jpg

CV mode in Mach3.
In General Config, enable "Stop CV on Angles >" and set it to 89.

[Trell]

Yep the CNC whisper done it again. Fixed it. Thanks again https://uploads.tapatalk-cdn.com/201...9543e73528.jpg
