New Slic3r Settings with firmware 0.65e

Hi All,

Has anyone had any problems with the new slic3r settings of GitHub for the firmware version of 0.65e? Is seems all the start G-code has gone and the machine gets itself stuck in a loop trying to heat the bed to an extruder temperature?

Thanks,

Hi Orm 141

Here is the start.gcode from the old profile:

G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
M140 S65; Set bed temperature
G1 Z5 F200 ; lift nozzle
G1 X2 Y50 F2000; Go to wait for warm position
M116; Wait for all temperatures
G10 P0 S205 R0 ; Set extruder temperature
T0; Select extruder
M116; Wait for all temperatures

Slic3r checks the start.gcode to see what's in it, and doesn't repeat what it finds there, eg G21, G90, M83 and the temperature settings. The start gcode mostly just sets the temperatures, which meant you had to change the start.gcode yourself if you wanted different temperatures, rather than changing them in the Temperatures part of the Filament settings. Also, it sets to use G10 P0... and then T0 - for 0.65e these need to be G10 P1... and T1, due to the change in defining the first hot end as T1 rather than T0. There is a bit more about this in Adrian's blog post here: [reprappro.com]
If you want to keep the moves to a particular position, just copy them back into the start.gcode part of your profile.

Also, there is a bug that we're trying to track down with extruder retraction speeds, which means that high retraction speeds seem to make the printer hang. Set the retraction speed to 30mm/s rather than 60mm/s for now.

Hello Orm 141 & droftarts,

I encountered the same problem on my Ormerod. I fixed the issue by replaceing the old start g-code with the following g-code.

G21 ; set units to millimeters
M107
G21 ; set units to millimeters
M107
M190 S60 ; wait for bed temperature to be reached
M104 S195 ; set temperature
G28 ; home all axes
G1 Z5 F5000 ; lift nozzle

It now works just fine.

this might be stopping me from making my first print. got directed here
