Extruder not heating soon enough
I've run into another issue with the firmware version 19.2.
When my print starts, for some reason the extruder does not heat up until after all the preliminary instructions are executed. That means that it cannot extrude even though the extruding instructions are being exeucted.
This was not the case prior to version 19.
My preliminary code is :
[[gcode]] M107 M190 S57 ; set bed temperature G10 P0 S195 R-273 ; Set tool 0 operating and standby temperatures G28 ; home all axes G32 ; execute bed Z-plane compensation at bed.g 4 points M83 ; set extruder to relative mode T0 ; select tool ZERO G21 ; set units to millimeters G90 ; use absolute coordinates M83 ; use relative distances for extrusion G1 E-3.50000 F2400.00000 G1 Z0.300 F9000.000 G1 X21.521 Y45.215 F9000.000 Any thoughts? Thanks again! Ciao, Bob
Either add M116 after the T0 command in your slicer start gcode, or add M116 to your tpost0.g file.
Thanks! I'll let you know if there's any more issues!
Although that did prevent the print from starting before the head was hot, it did not produce optimal performance since the head does not start to heat until the very end of the prologue code, thus causing a long pause for nothing..
In the past, the head started to heat at the beginning, I guess when the G10 P0 S195 R-273 was read, thus heating while the homing and leveling was going on.
Would there be any way to get the head to heat while the bed is heating?
Yes, change the M190 command to M140. Also put the T0 command before the G28 if you want to start the extruder heating before homing.
