Hi,
Firstly, thank you for creating this CNC. I have just finished building it and had no problems. All axis’ move and respond correctly, however, I have just uploaded my first g-code sample (just a very simple rectangle with a pocket hole built in fusion - similar to your tutorial video) and exported it to the machine.
This is where the issue starts.
As soon as my machine executes the g-code the y-axis and x-axis reverse and make a “clicking” noise. This continues to happen until the machine reaches its limits. It’s a really unusual issue but as a newcomer to CNC’s I wondered if you knew where to start troubleshooting. I have tried multiple g-code operations from fusion but the same thing happens (regardless of the operation type I.e. pocket or contour). Also, there is no material involved at the moment just testing...
I believe it must be g-code related as if I manually move the machine via CNCJS everything works perfectly. Would you be able to share a good-working g-code sample for me to try? Or do you have any ideas.
Thanks in advance!
Have you set up yourdriver to correct current for your stepper?
Hi,
I assume not as I don’t know what you mean by tout. I followed the tutorial by Topsie with the external stepper drivers.
What I’m confused by is the manual operation works perfectly, but as soon as I introduce a g-code file it reverses after a certain distance.
Is there a way of sharing a video, as I’m struggling to explain it.
Hi Harry i correct my post mistake do the auto correction from my phone....and my answer was for an another issue topic ; clicking noise from stepper
Hi,
I just wanted to upload a short video in case anyone can help.
I’m really struggling to find out what this issue is. Like I said the manual movement is perfect and accurate.
Any suggestions welcome!

So I managed to solve the issue to some extent.
The issue is with the dual Y axis jumpers. When I add the jumpers to duplicate the Y axis to the A axis this unusual issue happens. Does anyone have any ideas why this could be happening?
Thanks
Okay so I solved the problem, which was the jumpers for cloning the Y axis to the A axis.
I had to use two CNC Shields (with one arduino) to run the A axis. (Tutorials online)
But now it seems to be responding perfectly, so hope this may help anyone who has dual Y axis issues.
Oh sorry i just see your mail and your post...
Thanks for the tricks, I never got this kind of issue, surprising
