Update to marlin 2 3dp12

[Bluemerlin]

hi all,

I've tried upgrading to Marlin 2.1.2 using Clif's firmware and the firmware loaded ok, however when I press the home button in octoprint for the Z axis the z axis moves right to the top and the printer crashes.

I did the M500 and M502 step, am i missing something else?

It's a standard 3dp12 with an SN04 sensor.

Hello

I do not remember configuring a Marlin 2.1.2 for the Stock Hictop 3DP12.
To the best of my knowledge the last Stock Hictop 3DP11/12 configured firmware was Marlin 2.0.9.3 and one specifically for 3DP08.

Could you post the Zip file for me to take a look at and configure for a stock Hictop 3DP12.

I did find an untested non-Stock custom configuration of Marlin 2.1.2 configured on 3.16.2023.

[Bluemerlin]

Which file do you suggest I use for stock 2.0.9.3?

The 2.1.2 file I found was in this folder: https://drive.google.com/drive/folders/ ... RGN9fKYZUe

[Roberts_Clif]

I can configure Marlin 2.1.2 or any other version you want. If you want Marlin 2.0.9.3 that should work.

[Bluemerlin]

I'd love stock 2.1.2 if you could.

[Roberts_Clif]

This has not been tested..

Did not include baby stepping
Did not include Advanced Park

If you have any problems post with explanation will take a look.

[Bluemerlin]

Thank you, I'll give it a try.

I use Win Merge to convert one version configuration to another version,
Loading an older working version sub file example(Configuration.h From working version and version to configure.
Compare them line by line updating what you want. As you progress you may note they changed some variable names.

You can even download the Marlin source from Hictop though it is so old it will take a long time learning how convert it.
This is mostly what I changed in Marlin 2 versions. Ps I started with Marlin_Chip Luck's version:
I converted 06.13.16, HICi3-1.1.0-RC6-Bugfix though many Marlin 1 & 2 versions then said not much more firmware can do.

Add MOTHERBOARD, SERIAL_PORT, BAUDRATE, CUSTOM_MACHINE_NAME, DEFAULT_NOMINAL_FILAMENT_DIA, TEMP_SENSOR
Add TEMP_SENSOR_BED, PIDTEMP, PIDTEMPBED, @section homing, Mechanical endstop, Stepper Drivers,
Ect...

Then Difference between my 3D 3DP11/12 Printers and the Original Hictop 3DP08/12

My Hictop has a different lead screw
2mm pitch leadscrew = 200*16 /2 = 1600 (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)
Your Hictop has a Stock lead screw
8mm pitch leadscrew = 200*16 /8 = 400 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)

My Hictop has a TL-W3MC2 Proximity sensor Yours is a SN04N
#define Z_MIN_ENDSTOP_INVERTING true // set to true for SN-04N flase for TL-W3MC2

My Hictop has a Filament runout sensor
#define FIL_RUNOUT_PIN 19 // Configuration.h, instead of pins_RAMPS.h Y-MAX

My Hictop has a Second controllable Fan
#define FAN1_PIN 7 // Configuration.h, instead of pins_RAMPS.h

Ps.. Hope I did not miss any code lines, If you want to learn step line by line in Win Merge comparing the Configuartion.h
The configuation.h is the only code that needs to be changed to get Marlin 2 to work on our Hictop 3DP12 Printers.
The others for Our 3DP12 is for options like Filament Runout, Baby stepping, Advanced pause, Configure 2nd fan Control ect...

I've had issues with it failing print while doing the bed probe, could you change the below I've found here for a different printer:
https://3dprinting.stackexchange.com/qu ... 0512#20512


For Marlin firmware, you should check the setting PROBING_HEATERS_OFF in Configuration.h file:

[Roberts_Clif]

Have not been here for a while.

What would you like for me to configure for you???

[Bluemerlin]

I'm not sure, I keep getting failed jobs due to heating failure before it starts, even if I don't probe.

[Bluemerlin]

I've been doing more investigating, could you try turning off THERMAL_PROTECTION_VARIANCE_MONITOR
