Simplify3D User Forum

Hi, I've been using S3D for a few years now, and just recently decided I should learn to use the second extruder on my MendelMax 3. My first object eventualy worked out, but as it turns out what I was doing wasn't the best way. I had created 2 objects to be printed together, and used the dual extrusion wizard. I then ungrouped the two FFF processes, changed the global offset of one of them, and re-grouped the FFF settings. This got my print to work.

Now I'm trying to print a single object, but with one extruder printing the outer layers, and one doing the infill. Now no matter what I do, setting the offset on the process, or on the machine settings tab, I can't get the offset to work. If I change the Global offset I can move the entire object on the build platform (which is way cool BTW) but no matter what combination I use, it seems the individual toolhead offset settings are being ignored. My bottom layers and outside layers are on the right place, but my infill is exactly 33mm from where it should be. BTW 33mm is the distance between my two extruders.

I've tried 33mm on tool 0, -33mm on tool one on both the process, and in the main machine settings with no results.

Has anyone else had this problem? Also I'm using version 3.1.0

You should set the toolhead offsets in the firmware. That's MUCH better than trying to constantly account for a misconfigured printer in the software.

Compound, I'll try that solution. I wasn't even sure if the offsets can de done in the firmware, but I'll dig around & find it.

However, this still doesn't address the fact that the offset controls in S3D (at least version 3.1.0) aren't working. Since they're there I should be able to use them. I spent hours trying to figure out what I was doing wrong, only to conclude the software must not be acting as designed.

If you want the software to manually adjust all of the coordinates in your gcode file to account for incorrect firmware, then you just need to enable the "apply toolhead offsets to G-Code coordinates" option on the G-Code tab. It most definitely works, but again, I would highly advice against this. Just setup your firmware correctly and you won't have to mess with manually adjusting all your gcode files.

Ahh, that helps. I hadn't noticed that check box, or didn't understand what it does. I'll use it for a few prints, then when everything is lining up I'll input the values in the firmware.

I'd probably have done it in the firmware before but the manufacturer's guide didn't instruct to do it that way. They suggested doing it in the software (different software). I was just trying to follow their instructions, but using S3D instead & couldn't figure out why the settings weren't working.

Thanks!

On another site, I found a cleaner method.

It appears that Simplify3D uses a command that the Dreamer no longer recognizes, so it ignores it. It can be fixed as follows:

Under the Script tab, remove:

M612 X34.5 Y0.0 ; Set toolhead offsets

Replace that with:

M218 T0 X0.0 Y0.0;
M218 T1 X35.0 Y0.0; Set toolhead offsets

To save this as default, you can hit the "Update Profile" button, or "Save as New" to create a new profile with a new name.
