"2020 is hindsight." Release - 119r15
IMPORTANT CAVEAT
The
mpmd_marlin_1.1.xfirmware is NOT designed for the V2 model of the Monoprice Mini Delta 3D printer. Monoprice recently began selling a V2 model of the printer, and I doubt that this firmware is compatible. Please, do NOT try to install this firmware on the Monoprice Mini Delta V2 printer.
Helluva year, 2020. Good to be started on 2021.
Nothing fancy in this release, but we have some genuine improvements, I think. Discussion and feedback motivated almost all of the changes, and credit goes to @mulcmu, @BackwardEcho, @Jozer99, and others for their participation and patience in this update round.
Notable changes
-
the printer should no longer hang and reboot when cabled through its USB port without an open connection (hoping to fix issues #47, #48, and maybe #5);
-
a tiny error that would accummulate in the z-axis when the printer repeatedly tapped (probed) the print bed has been fixed (issue #38);
-
more information, relevant for delta style printers, is part of the
M114"position report" code and during theG29,G30, andG33calibration and probing sequences (discussion #46); and -
the printer now displays the A/D converter values with its temperature readings to make it easier to collect measurements used to create customer thermistor tables. Groundwork is also started for custom/ alternate thermistors and more precise and space efficient temperature tables (discussion #45).
Please note: when installing or upgrading, the firmware may not properly detect and correct errors in the flash memory used to store its settings. Bizarre or erratic motion is a strong indication that there is a problem with the settings. The M502 (load factory settings) command followed by the M500 (save settings) command should get the firmware operating from a known "ground" state.
