Will we ever see Simplify3D support the resume print and print preview features on the R3D printers?

Postby EL Cuajinais » Mon Apr 25, 2016 1:22 pm

Starting to lose hope here. I miss many of the S3D features but I won't do large prints without the resume print feature. Can anyone shed light on the likelyhood of seeing S3D support the R3D exclusive features?

It does it IF you add the correct start and end gcode to your S3D profile.
The last line of your start.gcode must be
M1001

the first line of the end gcode must be
M1002

We discussed this in the old forum https://www.raise3d.com/pages/community ... -resume-pr

Here is my exact quote:
Correct, best recommendation I can give is just use the start.gcode and end.gcode in your alternate slicer. That's where the magic happens.

Now, the thing is, in Ideamaker, the M1001 and M1002 are added to the start.gcode but not shown in the edit profile. That's why you may not have known about it. The best way is to slice a test file stl with Ideamaker, and then open that resulting gcode and copy the start and end sections- rather than looking at the edit profile and copy and pasting from there. Hopefully, that makes sense.

For example, on N2, this is the actual appended gcode for start take from a sliced file.

From that same thread explaining what and how the M1001 and M1002 are used.

“One thing that's not clear to me is why the M1001 and m1002 commands are needed?”

When a motion controller reads lines of gcode, it puts them into a command queue. It's a first in first out “buffer”. You must have this because an 8 bit controller cycle loop needs to plan ahead motion. The problem is when power is cut, the 8 bit micro memory is lost. Again, we have the front end sending gcode line by line to the motion controller. Due to power reasons, the steppers and heaters are NOT battery backed. So when power drops, that's it.

What those commands are (M1001 and M1002) are KEY markers in the print file.

The start.gcode sets the machine up for the print and the M1001 is the last line BEFORE actual print starts. This tells the Linux front panel LCD computer to begin recording the last acknowledged processed gcode line back (from what I can tell- have not yet gotten to the exact details). Again the function is, print starts. We need to know SPECIFIC lines and sections of the gcode that have significance. The M1001 is basically “print has started, now this is REAL gcode”.

Then the M1002 marker is in the END gcode. If during a print, you have not yet reached M1002, then we KNOW some print is still left. How much? That's only known by comparing the recorded completed lines VS the actual source file.

So when you resume a print, it plays back a MODIFIED start.gcode, that homes X and Y only, and then begins on the last line where it left off.

Then when M1002 is reached, we dump the log file because you no longer want to or need to resume that print.

Keep in mind that the longer time goes by before you resume the less likely the resume location will be unnoticeable.
