I finally did my first test print on my upgraded Anycubic Predator.

It still needs tons of tweaking, but I'm beyond excited that it even printed first try.

I was pretty intimidated to do my own home brew machine, but I love the predator footprint, but hated everything else. (Hotend, Control system, Delta Arms, cooling, etc.) So I decided to jump in the pool and try.

I want to first say thank you to the people on the forum that answered my questions. I was breaking lot of new ground here and was pretty intimidated, so thanks for getting me up and running when I got stuck.

Here is what I put together. Hayden Magarms, Zesty NImble V3 extruder, Duet3 mini 5+ wifi, liquid cooled hotend, Thermaltake liquid cooling system, Smart effector, PanelDue, relays controlling pump, and external fan controllers. I custom designed the cooling fan system based on a CFD duct system I saw on Youtube.

I am so jazzed to see it move. It felt like the eternal project and I hit a lot of roadblocks, but at least its running.

I realize now that I need to write an effective pre and post gcode, but that will be my next hurdle.

Anyway, just saying thank you, and can't wait to see this thing perform once I have the enclosure and gcode worked out.

I'm trying to post a simple question in Firmware and it keeps erroring out as spam. There is no spam content in it.

Any idea what is happening?

@gumby

Just to finalize the topic, I wanted to post that mixing pins from available headers worked like a charm.

PanelDue working now.

Thanks again to this community.

@gumby

Okay, I posted the same words in three separate chunks and none of them got flagged. Maybe the post was too long??

Just info for anyone that may be experiencing the same thing...

@Phaedrux

Thank You!

I wasn't sure... Then I can check that off the list and figure out what else it must be.

I have been using my homebrew delta machine, and I am still fuzzy on the mesh comp commands.

Here is what I have been using on my start gcode in my slicer:

G28 ; home all axes
G30 ; Probe Z height
G29 ; Probe Bed comp
G1 Z5 F5000 ; lift nozzle
M80 ; start pump

So here is my question. I saw running M561 cancels mesh comp. So, do I need a command other than my G29 to enable it? I was running a large circular shape, and my nozzle was getting way too close on one side, so that made me think maybe the G29 command only created the mesh file, but did not enable it. Does anyone here have insight on this topic?

Thanks in advance.

I changed a lot of variables, but it seemed to boil down to reducing acceleration and maximum instantaneous speed change.

It has introduced corner blobs, but now I will try to dial in pressure advance and accelerometer tuning.

So thanks for helping me work the issue out.

Gumby

It seems like it may be mechanical.

I have been trying several more fixes and will post when I come to some sort of conclusion in case it helps someone else.

I have my machine up and running, but have this mysterious problem.

When I grow my parts, the one axis is slanted. (See Pics). ( I printed one good one on my other printer to show what they should look like.)

I have no idea why this is occurring. I have quadruple checked every parameter I can find. I re-sliced, changed settings, tried changing the amperage on the motors in case there was lost steps, but it has no skipping, and everything seems smooth. It is also repeatable, which makes a lost steps issue seem unlikely to me. Has anyone else seen this, or how I may approach troubleshooting this problem?

Thanks in advance.

Thank you everyone,

I will look into all of that info.

Cheers,

I have a CNC machine that shows the active codes for the machine.

i.e. absolute/relative, pump on/pump off/ compensation, etc.

I really like having that info and I was wondering if that existed in the interface, or how to poll the machine for that info.

Thanks in advance.

Thank you for doing that. Not sure why my links were jenky...
