Re: Adjusting Tower Rotation with Alpha A/B/C in EEPROM?

Ugh, I just noticed my belts are chewed up on 2 of the 3 - bad enough they need replacement. I can tell this is from printing large objects causing the print head to come in contact with the bed far too often over this past year. When will it F!#@ING end?? I'm really getting sick of all these issues...

Easier said than done. I'd rather not open that can of worms. I've already gotten this far.

My question was - where is the Alpha A, B, and C in the PolygonHell Firmware (Repetier 0.81)

Re: Adjusting Tower Rotation with Alpha A/B/C in EEPROM?

I dug up some notes I took while I was adjusting the tower rotations. This may help you to figure out my thought process. It's pretty in-depth. The idea is to examine not only the towers, but the arc BETWEEN the towers, because problems often manifest right there. ⋅ For each iteration, I ...

Re: 40w Ceramic heat element too large?

For sure that is going to melt your effector platform. After scanning Ebay it looks like 6mm X 20mm is the standard for 40 watt and all the 20 watt I could find. You may have a tough time finding one shorter than 20mm. Perhaps using shorter spacers you could lower the hotend so that the cartridge c...

Re: Possible causes of unlevel bed?

I am an absolute noob: Question about tower rotation... do you mean a rotation of one compared to another? like a twist or torsion? This is my problem now. Or do you mean there isn't even spacing between the towers? or 1 or more towers are rotated so that one face does not aim directly to the cente...

I've been following your thread, not sure how much help I can offer. This machine is such a delicate balance between mechanical and digital it's hard to pin it down when something is off.

In addition to my continuing issue with leveling the bed through calibrating tower rotation (see other thread), I have been having a strange issue.

Re: Possible causes of unlevel bed?

Just a followup. I purchased replacement arms and carriage u-joints from SeeMeCNC and sanded those perfect (or damn near, if they're still a problem, i'll sand abit more). I think that resolves my Delta-Arm-Blues problems. But that didn't resolve my other issue with the bed. It took me a bit of work...

Re: Possible causes of unlevel bed?

just a sanity check, have you made sure that your glass is actually perfectly flat? I've purchased borosilicate glass before that wasn't actually flat. Yes, I have checked the bed, it's flat enough to not be causing the issue I'm seeing. I have run through the complete calibration process included ...

I had this problem until I fixed two things, hopefully they will be able to help you. 1) The instructions say to place a piece of kapton tape on the onyx heat bed where the metal is exposed, I found that it adds a very small bump that actually causes the glass to act slightly like a 'teeter totter'...

Re: Possible causes of unlevel bed?

Are you talking about the G0 Z0 X-45 Y-77.94 F2000 instructions for adjusting the endstops? Yes, I have - at all 3 rails, the bed is perfectly level.

But between the X and Z rails, and the Y and Z rails, there appears to be a highspot on one side, and a low spot on the other side.

Re: Possible causes of unlevel bed?

I've done everything possible to level the bed itself. I think the cause is something related to the arms or the top of the printer. Is there any other reason why some areas of my bed are up to 400micron higher than other parts??

While the right side of the picture you can clearly see the pr...
