MK1M (TEMP)

Disclaimers

Some speed settings in the firmware are currently reduced, they will be increased as they become stable.

Some issues relating to extruder feed rate and extruder skipping are known and being worked out on the MK1M. The current build is stable, however, excessive speed or retraction may cause issues. These seem to all be firmware related at this point and will be patched as they are resolved.

The MK1M's all-metal extruder assembly has been machined with very tight tolerances. This creates a very accurate extrusion system, however, it is very sensitive to extrusion and speed ratios. In other words, the Bowden extruder assembly on the MK1M is not tolerant when it comes to settings that force over / under extrusion.

Build

The MK1M build is very similar to the MK1 build, however, some steps have been done for you. You may use the existing MK1 build guide as a reference while we are in the process of creating the full MK1M build guide. This temporary document will note the specific differences between the two build processes.

Initial Checks

Power

Verify your wiring is correct prior to powering on the printer. Take special note of the 12v sections of the board this includes the main power in and the auxiliary power rails (where the Part Fan and Prove VCC are connected). Likewise, ensure the bed is bed is connected correctly, in this case RED is the POS and BLK is the GRD.

Once you have verified your wiring you may turn on power to the printer using the switch located on the PSU. You should see the LCD turn on.

Endstops

When the end-stops are not trigged the the end-stop LED will be illuminated. Using a piece of paper or other object test the end-stops by placing the object within the detection zone — the LED should go out.

Probe

Test your Z-Probe by placing a metallic object below the blue sensor. You should see the LED on the top of the Z-Probe illuminate.

Crossbeam

Verify that your crossbeam is straight, either by eye or by advancing the crossbeam to the top of the printer (resting it against the Upper 90 Supports. If you use this option, be sure to lower the crossbeam ~10mm before issuing a homing command as it will lift prior to homing (Safe Homing Feature)

Homing

When performing the first homing of the printer, be ready to either turn off the power via the PSU or hit the emergency stop located to the left of the selection dial on the LCD.

Using the LCD, navigate to Prepare / Auto Home or issue G28 via a Slicer terminal. Your printer should home itself.

Movement

Verify full movement of the printer by performing the auto bed level (ABL) routine.

Always make sure the machine is homed prior to issuing the ABL command

Via the LCD navigate to Prepare / Auto Level.

Via Slicer issue command G29.

Notes

Bowden

The MK1M is the first Odin to use a Bowden (top feed) style extruder. There are some differences between a direct drive and Bowden system that impact the use of the printer and printing.
