Files sliced in prusa slicer not working

in Repetier-Server
Hi.
Gcodes generated from prusa slicer wont work on repetier server. Seems like the print starts but the temperatures are never triggered. Nothing happens with the hotend and bed. 
What to do? Anyone? 
Tried with slic3r prusa version. That worked

    I have a PRUSA i3 MK3S and two delta printers. I use PRUSA slicer 2.0 and don't have any problems with the GCODE from PRUSA slicer and Repetier Server runs all three printers at the same time, all GCODE from PRUSA slicer.

    Repetier Server just sends whatever GOCDE is given it, so my guess is that whatever start GCODE you have in PRUSA Slicer isn't quite right?

    This is what my Start GCODE looks like in PRUSA Slicer:

    M115 U3.7.2 ; tell printer latest fw version
    G90 ; use absolute coordinates
    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 S{if layer_height<0.075}100{else}95{endif}

    Ok. Thanks. Tried a older file that i sliced in prusa slice about a month ago and that worked. I will try a reinstall av prusa slicer

    It's the firmware check that does it, I find the printer hangs when it checks the firmware. try removing that line form the start GCODE.

    Here's my start GCODE which 100% works on my MK3 & MK2s

    M83  ; extruder relative mode
M140 S[first_layer_bed_temperature] ; set bed temp
M109 S160 ; Set extruder temp before bed level
M190 S[first_layer_bed_temperature] ; wait for bed temp


G28 W ; home all without mesh bed level
M860 S35 ; Wait for Pinda to reach 35C before leveling
G80  ; mesh bed leveling 

M109 S[first_layer_temperature] ; wait for extruder temp

G1 Y-3.0 F1000.0 ; go outside print area
G92 E0.0
G1 E8 ; Purge Bubble
G1 X60.0 E9.0  F1000.0 ; intro line
G1 X100.0 E12.5  F1000.0 ; intro line
G92 E0.0

    fyi this also includes a pause whilst it waits for the PINDA to reach 35c - this can take a long time so be patient, or just remove the line if you don't want that.

    I'm using the 3.8.0 RC2 firmware on my MK3S (was using the 3.7.2).

    They changed the PINDA probe for the MK3 and MK3S. It now includes a thermistor and there's a table in firmware they reference for the hot and cold temps. If printing inside an enclosure you can calibrate a new table(s) because the temps will be higher, but I do open air printing and haven't had any issues.

    I did cut down the buffer size in Repetier Server from the default of 127 to 96. Marlin's ASCII Serial input buffer is 96...
