Hi Guys
I have a Polaroid 250s and use prusa slicer.
I load a model and the bed self levels the nozzle heats and states 'optimised' then extrudes a small amount of filament.
The machine then gets stuck on initialising and goes no further.
I have tried previously successfully printed files and get the same result.
Using head preheat it goes up to 150deg and shows that the head temperature is stable, no temp. reading is available during print,
I am currently using PETG at 240deg. But PLA setting does not work either.
I can't find anywhere to update/flash the firmware so am basically scuppered.
I did manage to get it to print by doing a filament change once but the print just stopped about 40% of the way through and said it was finished.
Any thoughts guys, would love some advice.
Cheers

Not sure how much help you'll get, they are a closed system so there's limited support outside of official channels.
I'd reach out to the polaroid support team.
 
Hi Vent
I checked out the thermistor and it is holding a steady temperature. I have found that old previous gcode works but not any written by the latest PrusaSlicer 2.6.1. What’s more strange is that I cannot see any difference in the code.
 
odd, try setting up a "new" printer in the slicer, see if the defaults have changed. different firmware's handle gcode differently (some only support limited instruction sets) so it maybe there's something new being added.
try slicing the same model and see if you can spot the difference in the new one?
 

RE: PrusaSlicer 2.6.1 will not work on Polaroid 250s​

Hi Guys

The attached zip contains two files the One called Bike Bracket works , the one called Hike Bracket does not.

Looking at the code these are the differences that i have spotted, all at the end of the coding.

Some new and some missing.

I would appreciate any thoughts on which could cause the print to not start. I assuming that the printer reads all code before starting to print.

2.6.1 has added;

wipe_tower_extra_spacing = 100%;

wipe_tower_extruder = 0;

wipe_tower_cone_angle = 0;

support_tree_angle = 40;

support_tree_angle_slow = 25;

support_tree_branch_diameter = 2;

support_tree_branch_diameter_angle = 5;

support_tree_branch_diameter_double_wall = 3;

support_tree_branch_distance = 1; support_tree_tip_diameter = 0.8;

support_tree_top_rate = 15;

overhang_fan_speed_0 = 0; overhang_fan_speed_1 = 0;

overhang_fan_speed_2 = 0; overhang_fan_speed_3 = 0;

overhang_speed_0 = 15;

overhang_speed_1 = 15;

overhang_speed_2 = 20;

overhang_speed_3 = 25;

mmu_segmented_region_interlocking_depth = 0;

filament_multitool_ramming = 0;

filament_multitool_ramming_flow = 10;

filament_multitool_ramming_volume = 10;

extra_perimeters_on_overhangs = ;

enable_dynamic_fan_speeds = 0;

autoemit_temperature_commands = 1



2.6.1 has removed,;

clip_multipart_objects = ;

ensure_vertical_shell_thickness = 0;

filament_minimal_purge_on_wipe_tower =

infill_only_where_needed = 0


Cannot see how to attach zip file.
 
you won't be able to tbh. the forum doesn't host files.
I can't tell what in there would cause issues.
try downloading an old copy of the slicer or a different slicer?
