I turned the hot end temp up to 200 and accidentally left the Web UI with a 200% speed, so the first layer was dropped down pretty quick while I was out of the room, but seems to have stuck Not the best first layer, but something I can work with, Maybe the Temp did the job. Thanks for all the advise guys.by unstable - Ormerod
I'll give that a go too. I have always tried to stick to the lowest temp that prints, not sure why.by unstable - Ormerod
I did manage to print a coat hanger from the gcode on the SD card, but only by dropping the Z axis until it almost didn't extrude, some of the first layer failed to print because the extruder blocked up but then later layers filled it in. Not ideal, but it just about stuck, still curled up on the corners. I'll try blocking the cooling ducts tomorrow and see what happens.by unstable - Ormerod
Printing PLA, 60 bed temp, 190-195 hot end. 0.24 layer. All the same settings that seemed to print fine before swapping the board. Not that I think it is the board, that's great and has made Z homing much better. I think it is over cooling the first layer.

Hi all, I've installed DC42's new sensor board and all seems to be working well, apart from the fact that I can't get anything to stick to the print bed I have a single piece of Kapton tape on the glass (200mm wide) and the nozzle is touching the bed fine and 'squashing' the print to the bed. But even the brim is lifting and getting stuck to the nozzle. I'm using the mount DC42 suggests : Duby unstable - Ormerod
It was probably more the lack of cooling on my O2, black didn't seem to lay as well. Increasing cooling and dropping hot end temp helped.by unstable - Ormerod
I too have been printing with Excelvan, Red and Silver PLA. And eSun black. All seem good so far. Black is a bit tricky but I suspect that is because it retains heat a lot more than the others.by unstable - Ormerod
Thanks Darathy. I had that design before changing to DC42's board, but wasn't happy with the fan duct as it often caught on the print. I like the new design from dc42 (Github) but want something that can use both fans, the one for the cold end (redirected from the heat sink) and the other fan controlled via gcode.by unstable - Ormerod
I know there are a few designs for the fan/hot-end mount with DC42's sensor board, but does anyone have something that makes use of a second fan for cooling? I have 2 * 40mm x 10mm fans, and would like to use them to increase cooling on the parts if I could. Ideally I want 360deg cooling.by unstable - Ormerod
Sounds good, thanks. And thanks for the board, it makes a huge improvement to the printer. Now I just need to install my ALU X arm.by unstable - Ormerod
Does the compensation persist across restarts? Or is it something I should do before every print? Up until now I've never used it, just homed XYZ and printed.by unstable - Ormerod
Quotedc42 I suspect the problem is that you still have the homing files set up to home Z in one corner, but you are now running 5 point bed compensation. Try changing the homez.g and homeall.g files to home at the centre of the bed. Recalibrate your G31 Z height at the centre of the bed, and remove the white squares at the corners of the bed if you still have them. Yep I went through them, all sby unstable - Ormerod

Hi All, I've just set up DC42's sensor board and am tweaking all of the config files. The final problem I have is that when I do Auto Bed Compensation the Z0 is too high, if I restart and do a Home all then Home Z it's fine, but after a ABC a Home Z causes the Z to be too far off the bed. Any thoughts? bed.g attached. M561 G1 Z10 F200 G1 X50 Y25 F3000 G30 P0 Z-100000 G1 Z10 F200 G1 X50 Y190by unstable - Ormerod
Mine turned up too, thanks a lot. Is it just a straight swap for ormerod 2?by unstable - Ormerod

dc42: Does this firmware version fix the cold extrusion bug?by unstable - Ormerod
OK thanks, so I don't need to go out of my way to make sure the shielding is restored. Another question, what is the theory behind a stepper controller being damaged if the motor is plugged/unplugged when there is power to the controller? Not knowing much about motors or controllers I'm intrigued.by unstable - Ormerod
My replacement Duet has arrived and I'm making sure everything is set up OK and there is no possibility for shorts. One thing I noticed is that the metal duet enclosure has quite tight grooves for the cables, which is actually starting to cut through the cables. I removed the aluminium foil and checked all the cables before heat shrinking them. Then reread the bit in the build docs that says tby unstable - Ormerod
Hi Tig124, I would be keen on ordering a few quick-set nozzles if you do find someone who can make them.by unstable - Ormerod
I have some regulators that I can use to replace the faulty one, but it's the stepper controller that is holding me up at the moment. 3 days now and no reply starting to worry if I will get a replacement before the 15th and don't want to have to return the lot to RS as I doubt they have spares.by unstable - Ormerod
QuoteTreito Confirmed Dave. I think so, too. Besides it was very quickly. If the company would have run very well and you decide to close it for the reasons that were named you would pronounce this earlier and you would take care about the spare parts and service. Maybe you even would do a big sale. Look at Vorty who ordered and bought a printer short before the shutdown. I have never heard fromby unstable - Ormerod
Thanks for all the advice. I've put it all back together and it seems to work fine, apart from the X-Motor no longer works. If I connect the Y motor to the X motor header, that doesn't work either, and likewise if I connect the X motor to the Y motor header it works fine. Could I have damaged the X motor driver? I'll try removing the Duet from the case again and see if that makes a differenceby unstable - Ormerod
I've removed the board from it's enclosure to check that nothing is grounded on the casing, and powered up the Regulator board on it's own without the Duet connected. I am still getting 10-11v on the output of the 5v regulator, so will contact support about a replacement. Although I think I do have some spare LM7805s, would support mind if I replaced the component myself? Or would that void warby unstable - Ormerod
Why do we use the offboard 5v regulator I stead of the onboard switching regulator? Is there any need for me to debug the offboard regulator if I can just use the onboard one?by unstable - Ormerod
My mistake, not "across". All seems fine now I'm off the 5v reg, it might be a short underneath, otherwise I think I have some of them regulators that I can replace it with. Will let you know how I get on. Thanks for help.by unstable - Ormerod
No I don't have anything else off the 5v rail. But the regulator output is pumping out 10v so I suspect that is the problem. I will try the onboard regulator to see if that helps.by unstable - Ormerod
I think I've managed to get around the problem. I've removed the ATX 5v jumper so the Duet isn't using the 5v regulator and instead am powering it using a USB cable into a mains USB plug. I've just managed to successfully print a replacement Z axis mount with no reboots at all. Will investigate the regulator later.by unstable - Ormerod
I've just put a multimeter across the 5v regulator and am getting a constant 10.4v... Am I doing something wrong here?by unstable - Ormerod
