I have asked on duet forums and awaiting reply, cross posting here to see if anyone has any ideas... Have a new Duet3 build wired up and working, done a test calibration cube which printed fine. However on longer prints the printer is failing after an hour or so (this is second occurence in a row now, hoped first was one off glitch). 02/06/2020, 19:42:57 Warning: Lost connection to Duet (Timeoby Via - Duet
Thanks for feedback... 2 Z motors - take it this will be no different to current system using smooth rods, I currently occasionally resync them but most of the time difference is negliable and accounted for with mesh levelling. 3 Mounting holes - Mainly asthetics using all 4 made it look very blocky which seems to be increased because of no smooth rod bearing mount to break this up.

I am in process of building my first completely designed from scratch printer (but utilising some ideas from other printers). I currently have a scratch built AM8 and going for a similar design but with some improvements and larger build area. I purchased some linear rails which were originally going to be used for Y axis but have instead gone for a VSlot gantry. So I was thinking of putting theby Via - Extruded Aluminum Frames
Hopefully last question now... My 24v fans seem slow when connected to PWM outputs. Always on powers them up to full speed fine but using PWM at full blast they are running really slow. Jumper set to use VIN, multimeter shows about 20v at PWM outputs when on.by Via - Duet
You're right, me being an idiot by not actually checking and just going on a spiky looking image Previously difference was quite excessive (+/-4mm at times) but that was with previous frame and Z axis was terrible (hence new frame). In regards to having to do 4 point leveling twice, I moved Z homing to center of bed (was previously doing corner) and this seems to have resolved that. So all iby Via - Duet
Cheers, AM8 is the metal frame upgrade of the Anet A8, had a cheapie chinese clone of the A6 so have ended up replacing most components and building the AM8 frame for it. It is 220mm2 and did a lazy measure of resistance including wiring loom, from the pads etc... does show ~1.2ohm. Will stick with old bed but thrown in a 12v PSU and MOSFET for now until I come up with something more permanenby Via - Controllers
Still getting grief with this but been busy putting together a new frame which is finally almost there so not had any time to dig into this much more. Attached some pictures to show the issues I am getting. The 4 point shots were from a few days ago in old frame using DC42 mini IR, attempt 1 and 2 are done straight after each other and this happens every time, attempt 1 is not a true reflectionby Via - Duet
I'm in process of putting together a Frankenstein printer using a duet Wi-Fi and an AM8 frame. I have got a 24V psu and have a donor heat bed from a leshp Z1 (A8 6 pin connector style) and a recently purchased MK3 heat bed from eBay. The eBay one is typical eBay quality and about as thick as a piece of cardboard. But most annoyingly half heats much faster / hotter than the other, putting thermiby Via - Controllers
Normally leveled at room temperature, have tried with bed hot as well in case any changes with heat but get less reliable results. Endstops are accurate. None noticeable, funnily enough I did have Y axis loosen yesterday which was noticed in test print on glass I was getting considerable binding, tightened that up after the print and moving perfect but that's when I could never get it homed.

I've been having problems with bed leveling since I've put in Duet wifi & DC42 mini IR. For the most part it is "annoying" but recently it is becoming more and more aggravating, I've enclosed entire firmware download including today's heightmap. This has never worked and always gives a report that would rival the alps. I use a build tak bed which is matt black with some white writing on. Todby Via - Duet
Quotedc42 Do you have deployprobe.g and retractprobe.g files on the SD card that you didn't create yourself? If so, delete them. Later firmware versions run them automatically when you send G30. Spot on. Removed those and can home my Z axis. Many thanks for your help Didn't think about those other than removing the lines from homeall which had been added. Almost there now, need to try and briby Via - Duet
Not a great video as would have taken too long doing each individually so this is pressing Home Z (with M564 H0 back in config)... At 3s X axis is in correct position and 6s Y axis in correct position (Y axis is set slower than X, if I had done manually that is where both would have stayed before G30). Then both X and Y move back to home before it begins to descend. (ignore squeaking of Z axiby Via - Duet
Quotedc42 G30 requires X and Y to be homed but not Z. The message in the original post indicates that is was a G1 command that was failing. You will need to have X and Y already homed for the homez.g file to work. X and Y are homed. Running G30 is what causes the G0/G1 error. Removing M564 H0 and then homing X and Y when running through homez script manually in console... G30 Error: G0/G1by Via - Duet
Adding S2 to G1 X20 Y20 didn't make a difference (it is doing this movement fine as X & Y are homed). Adding M564 H0 almost works... Adding that and homing Z did same movements as before, lifted Z, moved X & Y to probe point however it then moved Z up again and rehomed X & Y before begining probe but now IR sensor is no longer over the bed.

Got my Z axis moving properly now but for some reason will not home. I have normal mechanical stop switches on X and Y and they both home fine. If I try to Home Z it does the lift, goes to probing point and then comes up...

Went to do the changes this morning and as I was editing config.g noticed my steps per MM for Z axis seemed a bit high, looks like I added an extra 0 changed that and moving as they should be Now got to decide what I want more dual extrusion on gantry levelling, but for now that works so on to next thing.by Via - Duet
This is what is happening... Moving down seems OK (but noisy), I'll have a look at using E1 until I can get a 24v supply, leveling the gantry would be a benefit as well.by Via - Duet
Thanks, certainly didn't look or sound healthy but wanted to double check. I am running in 12v (24v on the list), it is an uprated power supply though and only 0.9amp motors so supprised it wouldn't be able to power them, but on that note when I set everything up through configurator I did put current down as 900ma, should I have doubled this for the 2 motors?by Via - Duet
Upgrading my Z1 (Anet A8 clone) with a Duet WiFi, some new steppers and other bits. So far have got X & Y homing OK but struggling with Z axis, but still working that out myself but may be back for some help if I still struggle. Main question though is in regards to the dual Z stepper motors, when homing X or Y it moves the Z axis slightly by the motors don't seem to move together, one moveby Via - Duet
