@dc42 hi all can any one please advise me how can i set the values of M92 for polar 3d printer and whether those values are necessary, the design is Y turntable with X moves as R which moves horizontally and Z moving up and down, i would say the turntable should move 360 degrees but my problem the shapes the machine currently drawing almost the model however the problem i face is in corners they come round instead of sharp corners it seems R moving shorter distances which result of not identical shapes.
version of my firmware
FIRMWARE_NAME: RepRapFirmware for LPC176x based Boards FIRMWARE_VERSION: 3.3beta1_5 ELECTRONICS: LPC176x FIRMWARE_DATE: 2021-03-31 11:33:17could it be a problem in the firmware release ? can you please advise the possible to work release ?
