Z Problem with Idex
Need help please.
My 2nd extruder in mid print appear to dig into previous layer and cause shifting problem. Had to cancel the print.
here's zooming in
[update] change the I30 to I60 seems to have solved the issue. is this related to this issue?
M906 X950 U950 Y950 Z980 E800:800 I60 ; Set motor currents (mA) and motor idle factor in per cent
I can't see why increasing the idle current should have changed anything unless the original problem occurred after you paused and resumed the print, and 30% idle current was insufficient to maintain the position of the effector in the paused state.
I didn't pause and resume the print
Agreed I also don't think what I did ( from 30 to 60) should fix the problem especially when the problem appear to happen during printing, so the active toolhead (T1) was dipping midprint. Strangely T0 actually holds its z position…
And also more strangely I don't have this Z dipping issue if I do single head printing only. Tested with both T0 and T1 and each of them successfully complete the print
There might be something happening during toolchange... I'm not sure
Dc42 don't worry about this one. I'm 99% certain it is my build issue. I know what happened and will post solution here once I worked it out so as to close this post. Just want to give you heads up. It's the bowden tube pressure buildup pressing down the hotend…
I have a very short ptfe betwee bondtech and e3d heatsink. Turns out I had used the wrong nozzle size.. I installed 0.25mm and when slicing I set it as though it's a 0.3mm nozzle… This result in too much pressure in the ptfe and bondtech never slips so it pushes down the e3d hence giving me false thinking that the z tower on right side appear to struggle...
