Cheapskate adjustment after crash
Posted: Mon Sep 15, 2014 8:49 pm
Hi all,
have had my new Orion for about a week. printing laser alignment tabs now,everything was working great.
I wrote 3 short scripts to help level the bed. each script moves the nozzle from the center to each post, about 0.2mm above the surface, and stops.
I then use plastic shim stock to measure the offset and adjust the carriage home switch screw to level Got the level to about 0.002" all around and center.
At the end, I had the nozzle by the right post at the perimeter. I homed the unit from that position, and the braided umbilical feeding the hot end got caught underneath the right cheapskate.
After several frantic seconds of nonstop grinding, i finally shut the power down.
Afterwards, while printing more laser alignment tabs i noticed the 0.075" hole in the center of the tab was reduced to about 0.010 "!
The bottom layer and other layer widths were fatter than normal.
After messing with the recipes, I finally noticed that left and back cheapskate had a lot of 'wobble' during movement. the left has about at least 1/8" play, and the back a little less.
The right cheapskate is still rock solid, no wobble.
So I downloaded the Max V2 manual to see how these were adjusted. It looks to me like there could be two things out on the left and back cheapskate.
* the 4 screws that hold it together
* the eccentric spacers..
So I plan to adjust these tomorrow ( printer is at work
)
I watch the short youtube video referenced in the V2 Max manual on how to adjust the eccentric bearings. at the end the final check seems to be to fling the cheapskate up and down and make sure the movement is free.
So finally, here are my questions:
1- Am I on the right path in attempting these two adjustments
2- Do I need to disengage each cheapskate from the delta arm so I can perform the "free movement" test shown in the video?
3- Am I missing any other adjustment necessary after this crash?
Thanks for any input. After a weeks play with the printer, I can see this is going to be a very handy device to have around!
