Change host to use E_STEPS_PER_MM of feedstock rather than extrudate?

Hello All

I have converted to Skeinforge 40 which requires the Extruder steps per mm in the firmware to be for the feedstock rather than for the extrudate (is there such a word?).

I still use RepRap host to send the gcode to my printer, and also to jig the axis etc when required.

The extrude function on the host sends the instructions in terms of extrudate length rather than feedstock length.

Does anyone know what variable I can change to reflect my firmware change?

Currently I have to exit a file manually, load and print the file each time I want to extrude a little, which is becoming a little tiresome.

As an aside, does anyone know of a more stable platform to use rather than RepRap host? It is extremely sensitive and has no recovery mode... I endu up having to reset the printer and restart the host a number of times when debuging my hardware

Use the new skirt function and you will never have to press the "Extrude" button again!

I use repsnapper to send g-codes from skeinforge 040.

BTW, the skirt function doesn't seem to work well with support. It prints right over the support. I'm guessing that I need to change the order but I haven't tried it yet.

I wish.

Unfortunately I had a slipping feed again last night (not sure why) and need to jig the extruder this way and that to re-prime/load new filament into it.

My question still stands if anyone has the know-how...

Re Skirt - the head moves right accross the print area, leaking plastic into it Previously the outline function would start at the corner closest to the home position. I have not looked, but I assume there is a setting for where the skirt should start...

anyone have the knowledge?

Just set your extruder feedrate in Host much lower, something like 150 mm/min, then use the extruder tab as normal.
