@fcwilt It's been a long time since I was last in contact with you. I had ordered some CNC parts and they were supposed to take a month or so. Flash forward to today and I might receive them Wednesday. Since then I have changed my mind on the hotend mount I had designed as the Hero Me designer came out with a mount specifically for my setup. I am unable to print with the materials that I need so I'll have to order those as well. I just wanted to touch base. Hopefully I can have all the electrical and mechanical parts setup in the near future. I could still use your help with the software when the time comes, if you're available your help and guidance would be greatly appreciated.

@fcwilt Well it looks like it will be a month or so before the parts are shipped. I started this project over a year ago, another month or so isn't too bad, I guess.

@fcwilt Yeah I plan to take another look at it at some point. It took me quite awhile to get that far. I figured when I was actually able to print I'd have to revise it. All I have at the moment is a resin printer. I don't trust it to last long.

@fcwilt I'm sure someone more experienced than me could have done a better job. Like I said I don't have any background in Cad and only starting using it less than a month ago.

@fcwilt I have the tool board with the BLTOUCH, Lgx, mosquito magnum, part fan, cooling fan, thermistor and heater setup and working.I designed the carriage and the mount. The duct was designed by someone on Thingiverse, * just modified my carriage to work with it.

@fcwilt Thank you you I appreciate it. Unfortunately I do have to wait for parts. I don't think there's a lot more I can do until I have them. At least none I can think of that makes sense without the build plate or heater.

@fcwilt Thank you again. I'm clearly over my head here. I thought I had a handle on this before I started. Unfortunately I have a lot of money plus time into this project, so I can't walk away from it. I'm feeling a little overwhelmed at the moment. I'm 45 and just started using 3d printers a little over a year ago. I don't have any background whatsoever in CNC, CAD, or 3D printing (maybe a tiny bit in general electronic/soldering). Anyhow, I'll try to implement your advise when the new parts come in. I'm waiting on a build plate and have yet to setup/order a custom heater. I appreciate your help, patience and time. Hopefully I can make some progress on my own when I get the new parts. I'm not feeling real confident at the moment.

@fcwilt I'm sorry I didn't realize that. I also realized for some reason I had 155 stuck in my head for Y center, when it was x center. I changed it to 185. I didn't have a mesh.g so I created one and added the G29 there. All the commands were added by the auto config. It was far as I had gotten before I started changing it with you.

How's this?

@fcwilt Thank you. Here's my configs again if you want to look at them. I'm working on sensor less homing and setting my Bltouch height from the bed next. It will probably be awhile before you hear from me again as I have to wait for some parts to proceed. I'm sure you won't mind the peace. I appreciate everything.

@fcwilt Thank you. I asked where to put the new bed config info because there is some there already. Do I keep what's there or do I replace it with the new config?

bed.g

bed.g @fcwilt My Y min is actually at the back of my bed. I don't know if that makes a difference. I think I know where this is placed in config.g but I have no idea where it is placed in bed.g. The E1 is a typo, I'm on my phone and was copy/pasting.

So it should be ?

@phaedrux I'm not understanding exactly how to figure out the variables given the example. G208 and G30 especially. I see the explanation and it makes sense, but looking at the measurements on G30 don't make any sense to me.

@phaedrux Thank you. I don't know why I thought it was labeled EO. When looking at the samples on the page you linked I'm not sure how that gets setup. I'm sorry I guess I'm a little slow here.

@phaedrux I'm going to use my old motors for the time being. They are working just fine. I have X and Y wired up without any issues. If you don't mind, could you help me with the dual z? I want to add the second motor to E0. I read the documentation a few times and I'm not sure if I'm understanding it correctly. My full build area is 310x370.

Again, I really appreciate your help. Thank you very much.

@phaedrux Unfortunately it didn't change anything.

@phaedrux I did try that and it didn't work. I tried my old Tevo motor at 850ma. It worked fine. The $200 worth of Moons motors are literally days old. I did see a discussion somewhere where they might have an incompatibility with the steppers. I think it was Stealth Chop in particular. I have no idea how to test that. I'm not an expert by any means but I generally make my way through electronics projects just fine. This is maybe the 3rd or fourth time asking for help ever. I'm just not having much positive movement with this Duet build. I'm not blaming anything, or anyone. It's probably my fault. Just putting it out there.

@unforgivenll Tried the new settings and the same thing happens. The motor just whines.

@phaedrux They were recommended for my original printer. I basically rebuilt my Tevo Tornado. There isn't anything original left on it except the extrusion.

@unforgivenll The Extruder is a different (LDO) motor and wired differently.
