Flip Pins on 2209?

[Joebus1]

Thank you very much for this wonderful guide. I have klipper installed and FFCP is running better then ever. When installing 2209 drivers do I still need to flip the pins to the other side or can I drop them in? Have the pinouts been changed via klipper?

Also, Can I set the Vref within klipper or do I need to set it using the pot?

1 More question. Do I still need to switch the two wires for each stepper or have you already done that in the cfg?

Thanks again!

You need to flip to match pins and use pot. Config file for tmc deals with direction, so no need to swap wires.

You are amazing! Thanks again for all your hard work. Pretty exciting getting these FFCP running better then ever. I've got 4 of em running of an old Dell Optiplex.

klippy.log Sorry to bug you again. I'm running into this issue when I run your START_PRINT I get the error Move out of range: 0.000 -16.193 0.250 [88.000] I have the Extruder 1 selected(Left side). It happens right after the purge line takes place. I'm not sure what I've got wrong. Only thing I can think of is something to do with Origin? I'm still learning so no idea. Thank you.

No need to apologise for asking for help, I just may take a while to respond as work is a little insane at the moment.

The origin is left corner at front of machine, which is different to the stock firmware origin of the centre of the bed. I did it this way to be consistent with all my other printers as they share macros.

As it is after a successful purge, the error is occurring as it starts the actual print, so this would indicate that the movement mode G90 (absolute) / G91 (relative) is being set to relative i.e. G91, the start macro sets it to G90 (absolute).

What slicer are you using and are you defining your own GCode?

[Joebus1]

I'm using Superslicer. Also I am using your configs copy pasted along with your START_PRINT script. Origin was set to half of max X and Y. I'm going to change to 0,0 and try again. Do you happen to have a superslicer profile to share so I can compare some things? Thanks again so much. This is awesome getting klipper on these.

[pedrsj]

That would also explain it, I'll update the instructions.

[pedrsj]

If you copied everything in the instructions the only difference would be the origin values.

[Joebus1]

Yay, Moving origin to 0,0 in the slicer fixed the issue. Only issue I'm seeing now is unless I activate the Left extruder(extruder1) manually via the macro in mainsail, The printer will heat up the Right extruder(extruder0) but not the left one. I don't remember this happening before so I must of changed something somewhere(swear I didn't haha) The attachment shows where I choose the extruder I want to use in SS. Is this correct?
I'm not sure how to set these either.

[pedrsj]

If I understand your question correctly, you are only wanting to print with a single extruder? If so, you need to set both extruders to be the filament you are going to print. With the available slicer variables, I can only determine the number of extruders in use by comparing the selected filament e.g. 1 if both extruder filaments are the same, otherwise 2. At the end of the instructions it shows this with a screen image. You then just select the actual extruder you want to print your model with.

I do the selection this way to avoid changing start gcode if you swap extruders.

[pedrsj]

The assumption of course is that you will always be using different filaments / colours when using both extruders.

START_PRINT BED=[first_layer_bed_temperature] EXTRUDER={first_layer_temperature[0]+extruder_temperature_offset[0]} EXTRUDER1={first_layer_temperature[1]+extruder_temperature_offset[1]} MESH=false EXTRUDERS_ENABLED={(filament_preset[0] != filament_preset[1]? 2 : 1)} # determine number of extruders by comparing if the filaments are the same INITIAL_EXTRUDER=[initial_extruder] # extruder you start printing with

Sorry for the long post:

I understand now. :) I believe I mostly wanted to know if my slicer settings were correct, but I think that is more for the SuperSlicer forums.

The funny behavior I experienced was when I wanted to print with just the left Extruder only. Before I fixed the origin problem I would select the left extruder in superslicer. Then slice and send it to mainsail and it would start heating up the correct extruder. After I fixed the origin problem I followed the same steps but the wrong extruder was heating up now. Then klipper would give an error about the correct extruder being under temp. To make it work I have to click the "T1" macro button in mainsail. Then start the print and it heats up and prints correctly. I would not think changing origin would effect that behavior so I think it must be something I did by accident somewhere.

I don't know what the heck I was going on about in the previous post. It was really late in the night and I am really bad at explaining things sometimes. Reading my own post and even I'm not sure what I'm asking. :) Thanks again for taking the time on the guide and helping me here. I hope to swap for a SKR mini E3 at some point soon.

Do you still have to manually select an extruder?

On changing the board be mindful that the creator pro uses type k thermocouples and not thermistors, you'd need extra hardware to use the existing hotends with most 3d printer boards.

No, It is working as it should now. I did a full power cycle of everything and copied over the config again, not sure what that was. I'm running the first full print now.

Thank you. I found this https://msptrick.blogspot.com/2022/11/flashforge-creator-pro-control-board.html and he happens to mention that :)

[pedrsj]

Other than you can, what is the reason to change the board

[Joebus1]

I figure I will spend half the price of the board on drivers anyways, then I got to spend time to flip the pins, The mighty board is a good dependable board but I assume newer might be better.

Mostly because I want to try ;)

[pedrsj]

Will be a cool project to do.
