Looking for the Malyan M300 Mini Delta 3D Printer Site?



These are not complete or official changelogs. As of this writing there isn't one.

Motion Controller

v51 - MC

“Pro”/V3 Only
v51 is not available for download. I prefer v50 anyways because the bed leveling probe points are further from the center of the bed. v51 for some reason probes 4 points in a small square near the center of the build plate.

- Modified heater runaway protection. If heating and sensor reading not changing after 30 second, will stop heating and (should) halt. (Something appears to have been happening when printing via USB that caused the nozzle temperature to continuously rise. Cause unknown but doesn't appear to have been a firmware bug that caused the temperature increase.)
- Fix cancel procedure. - (when pressing cancel twice during pre-heat, the printhead would start moving which required the MPSM V2 to be switched off)
- Fixed some USB compatibility issue with Linux/MacOSX system. Cura 15.##.# and Repetier-Host working on macOS. Cura 2.# and Simplify3D on macOS may not connect.

v29 - MC

V1 Only
- Minor bug fix.
- Add Mirror function which is intended for another model. The designed Y gantry is mirrored, so we can use M562 MY command to mirror Y axis.
M562 to mirror axis.
-A: If connection of X motor is wrong, caused motor direction inverted. Use “M562 X” to invert direction.
-B: If printed object is mirrored, you want to print letter “d” but get letter “b”. In this case, you need to install endstop to opposite end and invert motor. So use “M562 MX”, firmware will set coordinate to MAX when homing.
