What resin printer should I get?

  • +1 to the skipped steps discussion. Those offsets are from the print head somehow getting stuck and not moving when the stepper driver commands a move. Reasons can vary but often they are mechanically related.

    One very basic test is to move the head with your hands through its entire travel range on both axes (with motors off ie M84 or printer off) and feel the resistance to motion. Steppers of this size are not particularly powerful; you can overcome their force with your hands.

    Another possibility is that the acceleration is set too high: a fast direction change puts a lot of force on the motor. Try setting your acceleration really low, like 100, in the slicer and see if it still behaves that way. If not then there’s your handle on a parameter to tune.

    The poor behavior in the toast is probably a different parameter that needs tuning. I suggest getting the layer shift problem fixed before worrying about anything else.

  • Blender has the concept of unit scaling iirc. You might try adding a simple cube mesh and exporting that to your slicer and see what it reports. If you still have a difference in size then I would blame something in your blender file. My typical workflow goes from fusion 360 to blender to slicer and haven’t run in to scaling issues (besides forgetting to set the units in fusion 360 export to mm).
