while a replacement under warranty certainly is generous, to the OP: 1500mA at 24V is pretty much the highest (right, or is it 2A max?) you are to push the built in drivers, so feel fortunate that dc42 is being very cool about this. I run 24V on a delta bot and my currents are all around 800mA (obviously, the values are motor-dependent, but still, (I am inclined to say) it's unnecessary under normal circumstances to ever run the drivers at their upper limit…lest you get results such as the ones you've gotten. Just a thought for the future!

Have a nice day. Also, the intermittent direction changes in your Z stepper point to wiring problems for that motor. Before popping that driver too, please re-do the wiring and ensure you've got the correct pairs going to the correct locations as well as no intermittent shorting. Just in case you didn't know this: ensure your power is completely off prior to connecting or disconnecting stepper motor wires, as often doing so while powered up leads to blowing the associated driver, prob. the majority of the time (which is akin to an intermittent short).

HTH.

…engages a pinion to effectively apply brakes to carriages...? Sounds pretty trick and cool! Mind to attach some photos to show off this neat design? Looking forward to seeing it.

Have a nice day to all!

Hey there @Zesty Brian! It's Jonathan from over on your discord server. I, too, ran into this annoyance while performing similar updates to the firmware if my duet wifi board. What ended up working for be was to pull the SD card from the duet, copy over the firmware 2 firmware files as instructed on the page linked below, and then follow the recovery direction for fallback scenario #3 found in this page:

https://www.duet3d.com/wiki/Updating_main_firmware

Oddly, despite multiple attempts at adjusting the SetNetwork macro which uses the shory script described in the @updating to firmware 1.19 from below that which explains to disable the M552 S1 line of your current [SDcard]:\sys\config.g (simply modify the line to read ";M552 S1" by adding the leading semicolon) file before the dual upgrading of the firmware packages by issuing the M997 S0:1 from Paneldue once the files are in place and you have written the macro containing the M587 command with your appropriate details for SSID and password. Once all the prerequisite steps are completed and you go ahead with issuing the M997 S0:1 command, the last step is to run the macro file which will add your SSID to the known network list, then finally you MUST manually issue an "M552 S1" which will illuminate the LED next to the wireless component on the duet wifi board followed by a message displaying the IP address it ended up catching from the server. After all that is completed, you mustn't forget to navigate to the DWC server at that very IP address, go to SETTINGS->SYSTEM EDITOR ->CONFIG.G and edit the semicolon out from ahead of the M552 S1 line which in an earlier step we commented out.

Really hope this helps. Interestingly, I tried any 5 times to modify the syntax of the macro made called SetNetwork to no avail – kept getting error messages in console after issuing the macro. The only way I succeeded was to literally perform the entire Fallback procedure #3 in that linked site above from start to finish exactly as listed. Then suddenly the configuration settled in and didn't give me any error messages. YMMV.

Thanks so much for the response. Looking forward to chatting via email.

Happy Holidays to all!

Hi all, just thought I'd toss this message in here for two reasons:

firstly, I too have at one time desired this functionality and so it's nice to see some movement in the topic.

Secondly, because ask the necessary people are already involved in this thread that I would have direct messaged otherwise with the fact that currently I'm in the process of outfitting my second MetalMax delta frame with a newly built Diamond Hotend and am running into serious issues that I'm hoping one of the veterans in here can address:

• I'm using three Nimble extruders and had ordered from Shapeways a properly printed effector mount designed by the Zesty guys for this purpose. Initially, I mounted all the hardware and attempted to deploy it, only to find that the positioning of the extruders severely impeded the range of motion needed by the diagonal arms in order to reach positions that I require (such as dead center – homed). I posted this in the Zesty forums and it turns out the consensus is that I must be the first to have tried this since I built everything correctly yet still have this debilitating problem with how to achieve motion given the crowded airspace immediately above the platform which causes problems.

I continued my determination to get things working and was able to fashion a way to mount the entire effector from near the nozzle with the hopes that this mounting method, paired with trimming the Shapeways effector to remove the protruding sections which originally were there to host the magnetic ball/diagonal arm interface, would free up the effector to allow movement.

The result is that the effector IS able now to move, but is still severely limited in its range of motion. Depending on the orientation (of which there are three) I connect the effector at, I am limited thereafter to a triangle (roughly) which reaches to only about a quarter of maybe a sixth of the 300mm build platform and offset toward the side of the effector with the biggest space between adjacent extruders happens to be.

For this very reason, Stefan's original idea presented above would be competely desirable solution since, though I'm not certain if when using the regular bowden tube compliant mount the effector is limited from reaching the bed extents or not, but assuming it has full range, it would be a simple solution with which to run the Diamond as I so desire to do while removing the complications evidently introduced by attempting to utilize three RDD extruders to operate the diamond hotend with.

Thanks for taking the time to read this message. This makes me think that the delta may not really be a suitable platform for utilizing the Diamond Hotend, and brings to the forefront of my mind once more the conversation between Deckingman and myself where I had at one time expressed my desire to build a duplicate rig, based on his, and so on the absence of any workable suggestions which to try at the place I've been stuck at (as detailed above), I respectfully re-request from Deckingman the permission (and associated plans and bill of goods I would need to obtain) in order to follow the master down a tried and true path for Diamond success!

Is the difference between the newest version noticeable enough to warrant upgrading the two is got on my two delta printers, if the current ones are functioning properly?

Thanks for the response. Can you tell me by any chance what the difference between the ones you use and the LM76 version? If I understand correctly, the limiting factor is that the mounting holes should be 20mm spaced holes in a square pattern in order to mount the carriage adapters. Are there any other constraints to observe? Thinking about it for a moment, it doesn't seem necessary to span the entire length of the towers with rails since the lower maybe third doesn't ever get traversed…it's that a fair assumption? DC42, for instance, in your build, can you tell me the dimensions of your build and what rail length you ultimately decided upon just to serve as an example from which I can base my decision on? Thanks again. Also, from where does one obtain the new filament monitoring sensor system you've created. I've looked on your e-store as well as Filastruder but no dice.

Thanks.

Hi all,

been a while since I've been around here due to demanding curriculum in engineering school, but back and had a question with hopes that someone here will know the answer. I've searched around quite a bit, but still have no definitive answer to my issue.

I've got two MetalMax delta frames from tricklaser, which I really like due to the sturdiness and well machined extrusions. My desire is to upgrade these printers to sport linear rails to complement the PCB effector systems I've got. Through my searches, I've learned that the popular size of linear rails used for this purpose are MGN-12 HiWin rails, but then I came a post from a well known expert (mhackney) who at one point was going to embark on this same endeavor and his choice of parts were LM76 Speed Demon rails size SG size 10. I'm simply not sure what is the better choice, price being of no concern.

The unknowns, on top of the decision as to which rails to get are as follows: what length of rails do I need to order, and secondly, how best to attach the hardware to the frames I've got, which are (I believe) standard 2020 extrusions.

Any/all recommendations are greatly appreciated, as I'd really like to expedite the upgrade process but simply don't want to order the incorrect stuff and deal with scratching my head in frustration thereafter.

Thanks, in advance, for sharing your knowledge,

Jonathan

On second thought…maybe I just should leave it be and you can have a look upon receipt of it back to you. While I'm confident in my abilities with regards to utilizing my multimeter properly, I don't see really any possibility except for problems by opening up the possibility of it being a user damaged issue while it's currently DEFINITELY NOT that. Probably better that you pros have a look at it when it arrives back to you so you can determine how it could be that the two from the same package were DOA while the other works perfectly. It is interesting to know though, for future reference, what values ought to be displayed by the components.

Thanks anyway, and looking forward to the working replacements as I've finally been able to print satisfactorily every since assembling that first board which worked and has been working brilliantly. I can't say enough about what a great development this device you've come up with has been for my experience. Literally changed the game for me.

Cheers!

Funny enough, yes, that does actually make me feel a bit better off. I wish there was some way to figure out what could be stopping these two pcbs from providing the strain function…because otherwise they're perfect...lights go on a as soon as my thermostatic control hotend fan realizes hotend is above 60C, etc...just not giving me touch feedback which is a bummer cuz u dare not tinker with the one that works, but I desperately want to try the volcano high flow nozzle with my new printing abilities (compliments of your cool new effector release!). Any ideas on what to look for?

Thank you David for your prompt reply…and I must say, what a fantastic solution to the delta issues I had previously been up against. I say this as in currently printing with the one working pcb effector of the bunch and it is just astounding how well it's working for me, I must say. Though, I'm not able to currently obtain results like others have of variances after a G32 of next to nil, such as 0.007 like some users, but I am getting the best numbers I've been able to obtain yet with any other solution of approximately 0.031 (which is technically sufficiently low to work well, and he proof is in the results, which for me is finally having reasonably great looking output!! Thanks so much.
