Monoprice Maker Ultimate 2 Help & Updates

I own a Monoprice Maker Ultimate 2 and have been printing with it for over a year now. I plan on adding information here about setting the printer up and dialing in the settings to get the best prints. There are many issues I have had to overcome in this time and thought it might help someone else out there.

The help below is currently designed for the original firmware which is version 1.6 which has worked well for me. I have also included start Gcode for v2.28 which should work. Many users had issues upgrading to a higher firmware so I have not bothered doing this. If it isn’t broken, don’t fix it. That said if you encounter any issues with the stuff below feel free to reach out and I will try and help you out.

Printer Specs

Manufacturers name: Weedo F150S

Nozzle size: MK8 w/ M6 threading (measure new nozzle to ensure it is the same size as old one. If it isn’t you need to adjust your Gcode for the different height.)

This is something I had to figure out because I wanted to use the newest Cura version and the one included with the printer was v3.6, too old. The problem was the new Cura did not have a profile for this printer, only the one included by Monoprice had a profile.

What I did was I took the profile from Cura 3.6 and modified it a bit and added it into the newest Cura as a custom printer. This worked great. I had to solve a few more issues like the printer not wanting to set the proper heat level at the nozzle but those were all solved in this Gcode.

Cura Gcode

Start Code for firmware v1.6

;(* start.gcode for Ultimate2 (150S)*)
G28 ; Home extruder
G92 X200 Y150 Z165
G29
G1 Z15 F100
M107 ; Turn off fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
M104 S{ material_print_temperature_layer_0 }; set extruder temp
M140 S{ material_bed_temperature }; set bed temp
M190 S{ material_bed_temperature }; wait for bed temp
M109 S{ material_print_temperature_layer_0 }; wait for extruder temp
G92 E0 ; Reset extruder position
G1 X140 Y7 Z{layer_height_0} F4000
G1 X40 Y7 Z{layer_height_0} E23 F1000

Start code for firmware v2.28 (The difference is the “G92 X200 Y150 Z170” line)

;(* start.gcode for Ultimate2 (150S)*)

End Code for firmware v1.6 & v2.28

The 2 code blocks above will need to be placed into the custom printer settings of Cura.

You can get there by going to the menu Settings > Printers > Manager Printers.

If you do not have a printer added here add a new one. Select ‘Custom’ from the list and name it whatever you want, I went with ‘Custom MP Ultimate 2’ for mine. After you have that made click the Machine Settings button and add the Star & End Gcode into the respective boxes. Set everything else up in the screenshot the way I have it set as well. Some of the Gcode in the screenshots is hidden but trust me, it is all in there.

In the next screenshot all of this works for a stock printer. However, if you have changed the nozzle size of your printer you will need to adjust that here.

Slic3r Gcode

All that really needs to be done here is to change the variable names.

Start Gcode for v1.6 firmware (untested but should work)

;(* start.gcode for Ultimate2 (150S)*)
M140 S[first_layer_bed_temperature]; Set bed temp
M104 S[first_layer_temperature]; set extruder temp

G1 Z15 F100

M109 S[first_layer_temperature]; wait for extruder temp
M107 ; Turn off fan

G92 E0 ; Reset extruder position
G1 X140 Y7 Z0.27 F4000
