Welcome to the SeeMeCNC Community

I am the owner of a newly constructed Rostock Max v2. I'm in the process of calibrating my towers. I first manually adjusted my Z height, and I'm now trying to run the macros to get the bed level.

The first thing I noticed is that the stepper motor on the Y tower is really loud when running the macro. All three motors are quiet when I home them or manually move them in the x, y, or z directions, but the Y tower is making a pretty loud noise when running any of the macros. I don't think it was put onto the machine any differently from the others. They were all mounted using a caliper to measure an offset for the motor dampeners that I bought from Astroboy. They were all then screwed on using the blue thread locker.

Any ideas what could be causing one tower to make more noise than the others? Does belt tightness effect this?

Even with the noise, I tried to run the setup for the z tower. I tried adjusting the screw, but even with the screw backed out to the point of being wobbly (lowering the bed), the hot end would end up pinning the paper to the glass. I then tightened the screw back to the starting position and tried substituting 1 for the 0 in the macro for the z value (usually it is "G0 Z0 X0 Y90 F3500" but I put "G0 Z1 X0 Y90 F3500"). This was almost perfect, but i have no idea how to use that information.

I don't understand gcode. Does this number represent a height measurement? If so, what is the unit? Does this indicate that my towers aren't straight? The framing square I used when building my rostock is pretty crappy, so this is my biggest concern.

Just to see if the other towers were in the same boat, I ran the other two macros. The Y tower pinned the paper pretty hard, and the X tower actually felt pretty close to right the first time.

Well, I figured out that the binder clips were vibrating. It wasn't my motors making a majority of that noise. For now, I've put zip ties on the ends to keep them from having too much play.


I also figured out that when the manual says "You adjust the height of each axis by turning the end stop adjustment screw to the right to raise
the platform and to the left to lower the platform." it means the nozzle or the cheap skate. I thought it meant the build platform, so I was turning the screw left when I should have been turning it right. I should have been able to figure it out by realizing the homing tower would be higher, but it was a good learning experience.

You can easily remove the binder clip handles by squeezing each handle until one of the side pins slide out. Putting them back is just as easy. I did the same thing on my build to keep them out of the way.

Little strips of electrical tape under each arm helps as-well

I thought about the tape as well. The zip ties are working for now, but if I need to take them off to clean the glass, I'll put some tape on them.

I tried taking the handles off, but I realized I would have trouble getting the bottom handles back on blind. Maybe if I had one of those little dentist mirrors handy.
