The hose around the electrical wires from XZ setup dosn't go back into the slot in the base plate when running Y back and forth. This is causing me to loose steps actually stop movement.

Anyone got a permanent solution?

I added a video


The white is electrical tape that helped a bit, but still I don't see this working at all.

Yep, I had the same problem and the motor stopped because of it!!!

My solution was to file the borders a bit and attach some elastics between the hose and the hole where the reset-button cable goes through.

This way the hose always has a helping "hand". It's a cheap solution but it works for me.

Thanks jvalencia. I got the same suggestion from StepCraft and Rory from StoneyCNC too.

A clip showing how my fix works. I don't consider it permanently fixed but it works for now.

Oh good, too bad we have to rely on these type of fixes to make it work.

Other solution would be cutting the lower metal border with a grinder so it won't catch anymore and add duct tape to act as a "floor".

If I do it I'll upload some pictures.

I was going to try replacing the corrigated tube with some smooth pipe.

I had the same issue with my 2/840 and solved it by adding bowden (RC item) into the tube:

Beside this i have expanded the slot at the front by about 1cm:

I hope this is useful for anybody else with similar issue.

I had the same issue but it didn't cause the Y axis to lose steps, thankfully. I wasn't very impressed but it eventually stopped being an issue. I wouldn't be surprised to find if I opened up the machine that the sharp edge of the channel has worn the conduit away... :ohmy:
