Hello all, any advice would be great
I have the Star-A printer. Upgraded to the official firmware posted in May by Foobar. Originally I had Cura setup as RepRap as per the instructions set by the company. Prints weren't perfect but ok. After the first firmware update, my filament started blobbing (coming out thick and thin, not consistent, gear slipping as it was pushing out too hard. Next firmware update in May, updated, looked at the new instruction posted above and downloaded the cura profile. Instructions now state Marlin. Made sure Cura matched. Went to do a print and...(see the pink prints in pic 1)
Ive seen layer shift, but this is a whole new level. the left was take 1 with jerk and acceleration control. Right hand one shifted after about 1mm and started printing about 20mm off where it should. Both the RepRep and Marlin have extreme layer shifting. I'm confused as to what the cause could be, I've tightened all the belts and screws. the two Calicats that completed were printed out on the first firmware. Ever since then its been downhill and i cant figure out why.
Support has stopped relying to any of my emails. I'm hesitant to install the custom Marlin fork that Foobar has kindly compiled as i also have a laser engraver (not yet used but want to). My start G-code is:
;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time: {print_time}
;Filament used: {filament_amount}m {filament_weight}g
;Filament cost: {filament_cost}
M140 S{material_bed_temperature_layer_0} ;Set bed temperature
M104 S{material_print_temperature_layer_0} ;Set hotend temperature
M190 S{material_bed_temperature_layer_0} ;Wait for bed temperature
M109 S{material_print_temperature_layer_0} ;Wait for hotend temperature
;Next 3 values were set in the provided gcode profiles from selpic
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen
