While cutting foam with DW660 on tower, doing the intermediate training left side.
The Z-axis is shifting to far up or down, but only sometimes.
Sometimes when getting set for the next layer the Z stepper drives to far.

Allthread to stepper connector is tight.
Stepper just seems to drive to far at times?
Also seems that the gcode generated by Estlcam likes the move Z around alot.
Is that normal or necessary?March 1, 2017 at 3:05 pm #28697March 1, 2017 at 3:11 pm #28698

For some reason you don’t have a z rapid in you code. Double check it is in your settings.March 1, 2017 at 3:26 pm #28700
Thought that I had done that? But they were blank. dang.
On the tool list, looks like I need values in the finish feed rates also.
Than you mister Vicious … again!March 1, 2017 at 4:09 pm #28702
Working great now.March 1, 2017 at 4:20 pm #28703
Sweet, I know this kind of thing is very frustrating but you gotta love it when it’s a relatively simple fix!March 1, 2017 at 4:46 pm #28704
Simple for me. But I bet you spent a bunch of ttime figuring it out.March 1, 2017 at 4:54 pm #28705
Shoot we all used it as is for a year…the coming of RC8 made it worse. It was a giant group effort, but it was only 2 or three days of before both estlcam and the fusion post processor were fixed up and the machine worked even better than before.March 10, 2017 at 8:19 am #29170
So now I am trying to use SketchUp and SketchUCam for Gcode.
I notice, before I cut, that there is no Z rapid limits in the code.
Do I need to manually put it in?March 10, 2017 at 8:27 am #29172
You should really stick with estlcam or fusion with our post processor. Almost all other CAM depend on the firmware for rapid limits or treat all three axis with the same speed.
Other controllers have a rapid command built in, our ramps doesn’t do it that way, yet.March 15, 2017 at 7:56 am #29574
The other day I noticed that the back bearings on the tower, the bolts that were left very loose, were not in contact with the gantry tubing.
I tightened all 4 bolts up until a 3 bearings in each group were fully contacting the gantry tubes. Now the load on the bearings seems to be helping the Z stepper support the gantry.
So far no Z slips with a Z transit speed of 480mm/min
