@dc42 Hi all,

So in essence I need to make these

Along with the inverter chip and pullups.

I also need to cut the traces on the TMC5160 stepstick boards as shown here. Although I haven't worked out which to cut or not cut yet. I would be grateful if I could get some hints on that.

I can use the below document to calculate the necessary settings. Microstepping is fairly obvious and I would dipswitch these for easy changes. I think I just need spreadCycle and Not stealthChop (I'm not worried by sound levels etc) and I also I won't need hold current reduction. I'm not sure how to read the current settings. IRun =16 etc is a bit of a mystery to me at the moment.

I am at present gathering all the information together and will most likely EasyEDA a schematic and post that up. I am in no hurry. Thanks for the help, Gabbie

Hi dc42,

I too have burnt out a TR1 Fan on a Duet2 Wifi and have a replacement part for it. You mention Cold Gold Tape. Do you have a supplier that provides small quantities? I could only find rolls at £100 +. I wouldn't be needing a large amount.

Also a quick Awesome Thanks for helping with the flaky PanelDue return. The replacement is working a treat.

Hi dc42, I'm crazy and have treated myself to a 6HC (love Duet3D) but....

Going back to stepsticks, TMC5160, on the 6XD. Would a 74HC04 hex inverter serve to invert the Step line? and then the Enable polarity, selected via the jumper, would be bridged to GND being in the "right" position (The TMC5160 DRV_ENN is active low). Then all lines are pulled up with 10k resistors.

This is probably a little advanced for me but I would love to get the 6XD running as well. And I have the time to learn.

I also found the relevant information in the Duet documentation that answered my last questions. Sorry for the time wasting.

@dc42 Hi dc42,

I have decided to use the duet2 wifi but am still confused about the linear conversion module or 74HC board that goes between Duet2 and laser.

https://forum.duet3d.com/topic/12283/add-laser-for-duet2-wifi

Is there a board that is available through amazon?
https://www.amazon.com/Voltage-0-100-Linear-Conversion-Transmitter/dp/B00U7GJDVO

or is it better to self build through EasyEDA?

or Can I use zenors as in the analogue circuit design?

Sorry, this question is now probably in the wrong section.

I have trawled through all the forum but am still alittle confused as to which route is the best to take.

Thanks Kindly
Gabbie

Thanks, Gabbie

@dc42 Hi. Thanks for the quick reply. I was bought a 6XD as a present that was supposed to be fitted to a cnc machine. My plan has changed to a laser engraver/cutter but I still have the 6XD. I have a duet2 wifi which I could use using the logic converter as described in these forums, although I had other plans for it. I have some choices that I am thinking through.

But the short of it is that I could use stepsticks but maybe the DM556 would also be a good choice for a laser rig.

Hi all,

Just a general question really. I have a duet3 6xd with which I was planning to use TMC5160 drivers from mouser.uk (TMC5160SilentStepStick).

Do I just connect it up as stated with a 10k pull up?

"To connect a Pololu/StepStick/similar driver to the 6XD a 10K pullup resistor is needed from the Step/Dir/En lines to +5V" Is it that simple? I thought I'd ask before I shell out.
Thanks
Gabbie

Hi Phaedrux,

My 7i PanelDue has stopped functioning again. E3D replied saying to get back to the forum and post again with the issue. Any advice gratefully appreciated. Thanks Gabbie

@Phaedrux

Hi Phaedrux, I bought it from E3D on the 2022-05-19.

@Phaedrux

I tried the ribbon in CON_LCD but nothing. Alas. Do you think that is the end of the line?

Uodate: I removed the 7i from the case to examine the components for any damage - maybe I shorted it by being clumsy. I noticed slight marks in the circuit board. I rubbed to feel if it was a removable mark, maybe grease.

Reassembled and voila. Workings again.

Quite likely to go again though I think.

Thanks Phaedrux for all your help. Do you have any advice on a repair if it goes again?

Kind regards Gabbie

@Phaedrux

Thanks Phaedrux for helping me walk through this. I flashed "PanelDueFirmware-3.4.1-7.0i.bin". I will make a new cable up tomorrow and post the results. Kindly, Gabbie.

I have remade the cable. But no sign of life when reconnected to the Duet2. Below is a photo of the 7i working from the USB. Totally baffled at this stage. I have run M575 P1 S1 B57600 from the console but get no response either. Can I try the ribbon cable from CON_LCD? The Duet is a v1.02.
