Makerbot REP 1 dual help

[camstuff]

Ok I am new to this software - I have a REP 1 dual and have been printing but I need to adjust the start code. First it drives my extruder into the conner at heat up, I need to adjust the spot at which it stops to heat up - I do not run a HBP and want to turn that off - and last I need to stop the pre-prime before it starts as the PLA is just rolling up and sticking to the under side of the extruder in a big ball.

Thank you for any help.

This is in the Starting G-Code of the Scripts tab under the process settings. If you're familiar with G-Code you can edit it yourself, I believe most of it is commented to give you some idea of which each line does anyways so you won't be completely lost if you're new to it. You would just need to delete the line G1 E25 F225; prime as well as the two lines that control the heated bed

Thank you for the reply! Is there a way I can just copy and paste the start code created from Makerware into this area?

Simplify3D uses some placeholders, so there probably would be some slight syntax errors that would happen if you just copy-pasted it without revision. Can you paste the Makerware starting script here that you are using, and I can go through and change anything that may need to be changed.

ok I believe this is it

replace your S230 heating commands with

S[extruder0_temperature]
S[extruder1_temperature]

And the bed with

S[bed0_temperature]

Lots nicer for editing and customizing for different materials w/ out having to edit the gcode.

This^^

Ok thank you for the replays. So just to be clear... All is good to paste but replace the codes as stated in reply.

I went through and added semi-colons as well as changed the temperature variables.

I changed it from the makerware defaults to just extrude some plastic on the edge instead of making a long strip of plastic across the front. I've been using this for some time and have been satisfied enough not to change it for a while.
