Prusa MK3 will not even start printing.

Post by OldSaltyRC »

I found Kisslicer earlier today, and I liked what I saw on YouTube with regards to the wizards. So, I downloaded it, fired it up, went through the setup wizards. And went to print my first sliced print and the printer just sits there saying that it's heating up, but nothing else is happening. The extruder and bed temperatures don't register that it's been told to start heating?

When I did the Printer setup wizard it asked what kind of firmware I'm using, and for this answer I was not sure. My printer is the Prusa i3 MK3, and if I'm not mistaken it has a form of Marlin, but not totally sure. I chose 5D Relative E, not sure if this is my problem or not, I did switch it to 5D Absolute E but that didn't solve my problem either.

Here is my start Gcode (Prefix Gcode):

M115 U3.1.2-RC1 ; tell printer latest fw version
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 F1000.0 ; go outside print area
G92 E0.0
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line
G92 E0.0
M221 S95

And this was copied directly over from Slic3r start script that I normally use.

Any advice is greatly appreciated.

Thanks.

You have to change the placeholders. Those you mentioned only work with slic3r.

Use <BED> instead of [first_layer_bed_temperature]
and <TEMP> instead of [first_layer_temperature]

left to the window where you enter the GCodes is the list of the placeholders

If you have a look at the preconfigured profiles: http://www.kisslicer.com/preconfigured-profiles.html you will see there are profiles for the Mk2 and even a bed STL file which should work just fine with the Mk3.
