I've been up and running for five days and I have made some projects with success. Yesterday I ran Carmichaels guitar neck (from the project page in Easel). Everything went well but suddenly I heard something went wrong - I rushed to the machine and saw it had gone off path. Today I started over with the neck again and everything went as expected for two hours - then it went all crazy and took totally wrong paths. I would say it's related to the Y-axis steppers but I have checked all connections - and double checked (and I will do a triple check).
i had a similar problem. the vwheels weren't tight enough and slipping was occurring.
check your belts and v wheels
one thing to highlight. After I did this modification, i haven't had any slipping wheels
Can loose V-wheels really inflict that much? Belts are really tight.
Just watching this thread because I was carving something and the X axis appears to slip about 1/8th an inch after running fine for 2 hours. Lost the piece, but I can save most of the wood for another project.
That could be the problem. I have been testing it on smaller pieces and moved the steppers back and forth for some hours - nothing wrong. Have also checked cables and connections. A newbie question: how do I calibrate? Link?
Depth per pass was 0.7 mm.
make sure you do not over tighten the belts either.There is a thread where someone used a fish scale to adjust them.Also if you ever get any obstruction and the rail stops moving hit that panic button right away.I am still working on getting one and I regret it as the motors ate my belt and it broke. not very good. have fresh new belts on hand so your not out.
Continuing the discussion from Going off path like crazy:
I haven't got the X-controller. I will try to calibrate it.
@StephenCook: in what way can to high tension? Can a obstruction eat them? Are they available from Inventables?
I had accidentally left my suckit in the path and it caused the y axis to halt but the motors kept on spinning. Made a loud grinding noise. It ate the belts just enough that I didn't notice until they broke.having really tight tension will make them too stretched and break more easily.
Also make sure your tension is the same on both sides of the Y axis.
I have calibrated the stepper motors and it works fine. Thank guys!
