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.
ie gcode:
G01 X17.8000
G03 X13.6950 Y106.0841 I0.0020 J-6.5295
G01 X13.8957 Y105.8381
G00 Z21.0600
G00 X13.2117 Y10.1119
G00 Z13.5600
G01 Z10.0600 F180
G01 X31.4949 F900
G01 X32.9917 Y11.5406
G01 X11.4127
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.
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.
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
