Circle Ovality Issue on 60w Chinese Laser 500x700 - pulling hair out!

I give you all the credit man! My Y axis was squashing the circle initially, it seemed that by keeping X backlash to 0, and Y to .2mm.... It fixed it. Fingers crossed this doesn't mess anything else up, I only cut circles for this lol.

Thanks again man! Your input was key!

Well done mate... Dont play around with backlash adjustments too much, they cause distortion just like your first image squashed circle

I m setting the block height to 50 or more (original value is 50 and it seems to work well) i have no idea what the block handle does and no where there is any info about it, but it fixed my issue!

Congrats again... and good luck, glad these settings helped you find your own fine tune...

try larger circles and different speeds as well, if you have any other issues or your adjustments are for smaller circles, it may cause headache in large ones... fixing at large scale is the key as you go bigger and getting to a smaller error margin, it becomes more precise... if you know what i mean, 0.2 mm error in an 8mm circle will be greatly amplified in a 250mm circle! be careful with those values...

also for smaller circles there are some adjustments for backlash issues in config (s) / system settings / general settings /small circle limit... each option (small circle sizes up to 8 mm? is defined but you can fine tune them to your machine) has different speed value...

Cid you ever sort the circle counting problem out. If so what did you do.
