Unresolved Issues with vertical circles

I have some sort of calibration issue that I can not seem to fix. I can not get pieces to fit together correctly when they print apart from each other. For instance I tried to print a box with a hole for a switch and an outlet on different size. One hole was on the Y axis the other on the x. Both vertical and both printed like ovals. I can add pictures if i need to for further explanations. Thanks in advance.

 

Sounds like you'd got a loose set screw on one of your axis pulleys. Tighten them up

 

I would say oblong in the x. So they are short and wide ovals. i also just tightened both y and x axis pulley gears and they were already both super tight.

 

I am testing a 20 mm cube right now i will upload the results

 

Well that's the problem, it is off by 3mm on a 20 mm test print, so 15% undersized on the z. So how do I fix that?

Thanks for the help so far.

 

I am not 100% sure, but I have had the printer since april of 2015, and from my understanding it has always been off as I am describing in the thread, just didnt really notice because I just printed trinkets, but not trying to print functional things, or fit things together from my 2 printers, I have noticed the problem.

 

Yes I did, does the r1 plus say that on the glasss? or does it just have an R1?

 

Well that sucks lol.

 

I will do this when I get home from work today. Thank you guys very much.

 

when I counted I got 22 threads per inch

 

If your Z steps per mm are set to 2267.72 it will be about 10% short from the expected 2560 from M8. Flash your firmware to v3: http://guide.robo3d.com/Wiki/ROBO_3D_Firmware_Release_Notes
