The Z axis lowers into the material while the X,Y axis’s are moving. I am attempting to calibrate this yet again. During the test pattern test at the end of the calibration process the Z axis extends into he material while the sled is moving toward the first corner cut. It keeps extending/plunging until the router bottoms out. The Z should not even move until the sled gets to the first cut position.
Also as a separate issue, or it could be related, (this sometimes happens) when calibrating the Z axis, I set the bit to just touching the material. I then press “Define zero” The Z axis then retracts a few mm. When I go to mill a file, the Z retracts again a few mm. When the sled moves to the first cut position, the Z axis extends back a few mm but does not extend the full length of the total retraction so it cuts air.
Why is this doing this? I took out firmware version 1.12 and put in 1.11 and GC 1.11 and still have the same issue.
I don’t know why it would be doing that… but if this started happening after you upgraded to 1.12 then I would try wiping the eeprom prior to loading a version of firmware.
I had some z-axis weirdness when I upgraded from 1.04 to 1.08 (when .08 first came out) and that weirdness persisted when I tried to go back to 1.04; I fixed it by wiping the eeprom, loading 1.04 and recalibrated.
I’d try wiping the eeprom prior to loading 1.12 and see if that fixes it.
dlang, I’m not sure I understand. Yes, the latch is closed and adjusted (I’m assuming your talking about the latch one the router base). What I mean a when I describe the Z axis lowering during X,Y movement, I mean that the Z axis motor is turning and feeding the router into the material. The router is not lowering because it is loose.
Update…
I wiped the eeprom. reloaded in firmware 1.11. I went through the calibration steps. When I ran the test pattern and got my measurements, I attempted to enter the setting but got an error something about the measurements not working or not being acceptable. I forgot the exact wording. I ran the test pattern again, entered the results and got the same error message.
I then ran the mtn.nc file I got from Bar. It seemed to run ok except it wanted to make 4 passes that at the 3rd pass had already bottomed out the router. So, I wonder if that is just a file issue and not really a Maslow issue.
Does anyone have a simple File that I can setup the milling process myself for a 5/8" stock? Something simple that will also test the machine.
I just had a similar issue to this, not sure if I should start a new thread or continue this one.
I was trying to cut out the first sled, and the maslow isn’t always waiting for the z axis to come to position before moving x-y. A few times it was moving at +.1 instead of the +.5 saftey height, but right after it cut out the profile for the inner circle, it moved to cut the outer circle and left the bit at about -.5, dragging a huge cut into what would have been the sled.
Any ideas what might be causing it if it isn’t eeprom?
I would suggest to open a new topic as this is not marked solved and might be relatete to FW/GC 1.11 and I hope you are at 1.18.
Makeing a new topic will give you more attention then a in a 4 months old one.
