Re: Kossel - all axes calibrated, but height is wrong - 8 years ago
The tooth count was my issue. Thank You all (very belated) for your help. I have noticed the MakerGeeks has stopped selling this kit. Based on my experience with them and the kit I refuse to do any business with them. I currently have replaced most of the parts on this kit. Adrianby AdrianW - Delta Machines

All I have to say is OMG. I put a mark on the pulley and told the printer to move (5 rev worth of distance). The mark better end up in the proper place. I will count the teeth. My fudge factor make a steps/mm number is so close to your calculated number that this must be the problem. It is worth taking the printer apart to count them. Thanks for your insight.by AdrianW - Delta Machines

dc42, I have measured the belts, and the pulley teeth. all as it should be, 100 steps/mm. I have read that MakerGeek may have given me the wrong motors. The current for these is around 400mA in steed of the suggested 1500mA. The jerk and acceleration is a good Idea. However, I run the printer very slow because the extruder can't keep up.by AdrianW - Delta Machines

If you have the Injection moulded parts they are VERY loose on the frame. I sent mine back and found a supplyer for vertex parts for the 20mm frameby AdrianW - Delta Machines

AndyCart, I am using Belts an pulleys. I have GT2 Belts, 16 Tooth pulley, 200 steps per rev, and 16 uSteps per step. 6% off is just odd. I thought I was skipping steps. But after setting the current, tightening belts, and slowing the travel speed nothing changed. I adjusted my steps/mm to 94.1 based on actual measurments. So I am 5.9% off. Now I am at 25.04mm when I set a Z travel of 25mmby AdrianW - Delta Machines

I am having some similar issues. My X and Y are calibrated almost perfectly. However my Z hight is about 6% off. I can make a 25mm cube. The hight is 26.35mm. The X and Y are 25.00+/-.03. If my steps/mm where 80 insted of 100. I should see 31.25. I tightened belts and verified my that my steps/mm to be 100. Anybody have an Idea where I should go next?. I am thinking my current settingby AdrianW - Delta Machines
