S3D Doesn't know Table Size...

[ftherrmann]

Bought S3D yesterday. I put in a support ticket for the table size problem yesterday and also searched the forum and also watched some S3D setup videos that deal specifically with S3D and the FF Creator. Still haven't found the fix for the problem.

Here's my setup...

Flashforge Creator Pro

Here's my problem...

S3D thinks the table is larger than it actually is and does a start cleaning extrude to the left of the table. ReplicatorG knows the table size and works correctly. I've checked the EEProm offset settings in the CreatorPro and they are correct.

I've tried the suggested startup code given on the S3D website for situations where the left extruder starts too far left of the table. The only result I saw was that the start begins somewhere in the center of the table. (X axis) Also note that both the left and right extruder start too far left of the table.

Given that ReplicatorG knows the size of the table I believe I can assume that I'm have a standard CreatorPro build table.

GIven that S3D has a default setup for the CreatorPro I should assume that the problem lies within S3D. I've also tried the Creator preset and got the same results.

I'm new to 3D printing and don't know much about G code. However my guess is that there is a line in the startup code that defines the start x,y,z position of the nozzle cleaning extrude. The initial left nozzle height movement appears to be working correctly. i.e. table comes up and left nozzel touches the back right edge of the table.

How do I fix this?

This is intentional. S3D cleans the nozzle just off the edge of the build platform so that you don't get a big mess on the table. Then it moves right onto the table edge to wipe off the extruded plastic, and then begins the print.

Sounds like it is working exactly like it should. But yes, you can always edit the starting script if you want different behavior. For what it's worth, the default routine works very well for me.

I can confirm that the default behavior works for me, as well. Like Joe said you can alter the start script in the scripts tab.

I also have a Creator Pro and that is the way S3D does it.

To stop it from extruding filament before the print off the bed, under Scripts tab, remove this line: G1 E25 F300 ; purge nozzle
that will fix that issue for you.

I also have a issue with S3D being not centered with my print's when it starts to print. On S3D screen they look centered, but they end up being about a inch off. Wrote them 2x but neither response was any use to be honest. I have tried a few thing's but it's not such an issue at this point unless I'm doing full bed print's

Thanks for the posts.. I was comparing it to RepG and the nozzel cleaning off the table threw me. S3D seems to work fine now, just need to get my table and extrude temps figured out.

Thanks,

Fred

If you look at the Gcode tab of any of your profiles, you'll see the build volume and Origin offsets. Check that these reflect the capabilities of your printer and that the origin is in fact in the centre of your build plate.

Once you've got these right, then amend the start gcode lines that control the extrude and wipe.....
