    • RE: Motors working then chatter before and after homing...

      Ok... I have some good news and some bad news lol..... The good news is you guys are awesome and have saved me from losing my mind.

      The bad news is im a stupid idiot.... The chatter is in fact coming from the one z motor that is connected. I had forgotten that one z motor was plugged into the duet board while the 2nd z motor is plugged into the duex expansion board. I only unplugged the ribbon cable of the expansion board to eliminate everything on it, thus forgetting the one z motor on the main board. and im going to guess that i have a crossed wire from the breakout boards to where it finally connects to the board causing the non moving motor.....

      i feel like an idiot... as i said in my first video that was the only thing i had changed lol... so i should be able to bump all the speeds and current to the x motors back to where they were if i want... And now fix the z motors and finish the install of the probe.

    • RE: Simple G code question (reprap3firmware)

      Problem Solved:

      Went to take a pic and was verifying the wiring and noticed on one of the breakout boards i had two wires backwards... Switch now works as it's suppose to...

      Once again i just need to take a break now and then and stop spending 10 hours at a time working on this thing frying my old brain hahaha.

      Thank you guys... Now i just need to figure a way to tighten the carriage belt without redesigning and reprinting some major parts... then build the bed, then start printing....

    • RE: PID Tune never completes

      Sorry it's been a while since I last posted. Ive been busy trying to find a job, doing interviews and had a death in the family recently as well.
      As for the hot end not getting up to temp, it has been resolved by reprinting that fang and making a better cut this time. Once that was resolved i was able to attempt a first print, which of course was a calibration cube so i could start dialing in e step accuracy, acceleration and jerk settings etc etc.
      Well, before that could happen i had to dial in the z offset of the bl touch to get it to lay down a first layer... I really wish the babystep UI would give you more options for adjustment like the move UI gives. Having just one option at .02 takes forever to get close. In any case its printing but im still squishing a bit much so im still trying to dial that in as each cube was being printed...
      IMG_4289.jpg

      After messing with the printer for about 14 hours straight that day i had 4 cubes printed. I was dialing in extrusion multiplier, the e steps, the offset, some ringing... and was getting closer but i went to bed.
      IMG_4294.jpg
      The next day i fired the printer up, fired up another cube after making some more tweaks. I had my face down near the glass to observe the first few layers to adjust the babystepping more precisely when i heard a bang that startled me and I watched the glass crack from one side to the other. I was able to let the print continue and did get a completed cube from it but the glass (my 2nd one) is toast. The first glass has an extremely small barely noticeable crack and could be used again but i've decided on something different. I am just guessing here, but from a cold state to 90c on cheap annealed glass was destined for failure. I had planned on dialing back on bed temps once i started getting consistent prints but 90 is where it was sticking good for just glass at that moment.
      Major Crack.jpg
      After this i just decided to custom order some borosilicate glass. The first place i found for my custom sized bed they provided a quote of well over $600. They said boro is stupid expensive but for $40 dollars they could sell me tempered glass and should be fine... reluctantly i said ok and ordered it not wanting to spend over $600. The tempered glass would be about 7 days to have made.
      The more i thought about it the more it was bothering me as ive seen boro glass offered for smaller printers dirt cheap so i decided to keep looking. I found another place online that is located about 2 hours away in another state but their site said they have many sizes in stock. I called them up and asked for a quote giving them the same dimensions i gave the first place. He asked what thickness. Having noticed some of the smaller printers were using 3.2mm boro i opted for the 3.8. He came back with a quote of $125! I ordered it and immediately called the other place back and cancelled the tempered glass order and told them about the quote differences for the boro.
      So, im sitting here dying to dial this printer in more and i have to wait 7-10 days for this order at which time i have to drive over and get it mind you 2 hours away. Shipping was out of the question since ups is charging by size now and not just weight, not that id trust them with a sheet of glass anyways.

      I have to give a HUGE HUGE shout out to @fcwilt who helped me completely re-write all my gcode and sort out bed leveling with my setup and mesh compensation , breaking out functions to separate files rather than shove everything into the config file. We spent lots of time on the phone, answering questions and emailing back and forth. Huge thank you to him. I believe once the boro glass is installed the rest will be easy peazy (knock on wood).

    • RE: Home Y wont home...

      That solved it. Thank you sir!

      Now to decide whether to configure gcode for the bl touch or build the bed first... id rather test it without the bed so i dont smash anything lol.

    • RE: Setting Up Input Shaping On Custom Printer

      @Phaedrux
      If it only has to be temporary then I will use the ribbon and bypass the cable chains I guess.
      I will try to find time to do that this weekend. Then I will try to get the necessary Gcode added.

      I think that solved it. i need to remove the hotend from the bmg so i can heat it up and tighten it down for the first time... then i will try to extrude and set the esteps for the extruder.

    • RE: 3d Benchy Question

      @droftarts
      in S3D its called outline direction and the options are outside-in, or inside- out.
      Mine is defaulted to inside-out.

      The print i had going last night finally finished. I will implement some of the changes suggested in the thread now for the next print. Its very close to being dialed in. The part last night came out great and was dimensionally accurate. It had very few minor defects that doesn't affect the usability of the part at all.

      Will make the changes and post the results.

      New probe bracket installed and much better clearance now. Dialing in babysteps again then i think i'll try one of my larger prints.

    • RE: Revo 6 PID tuning just hangs

      I think this is finally resolved ... This was giving me fits cause it was so intermittent. But when I checked all the connections they would show ok. Finally during another continuity check, the intermittent connection finally revealed itself despite showing good several checks prior. It was a bad crimp. a simple bad crimp that just over time failed. Ichecked that particular connection several times.
      Thank you everyone for all your patience and guidance which did help me make a few corrections to some gcode and updates.

    • Setting Up Input Shaping On Custom Printer

      A few of you may recall my large printer build I did. Thanks to all the help here getting the gcode all worked out the printer is printing but its always had a bit of minor ringing in it. Im guessing a lot is just due to my design as i'm no engineer, but also a lot has to do with the table its on not being as sturdy as i like but it is what it is for now. Coupled with the sheer size and weight of the printer and not a perfect design, it has ringing.

      I have decided to try input shaping to try to minimize the ringing. So I have a few questions before I start. I have purchased a few lis3dsh boards and even the adafruit board in case there are any DOA's. I have bought some ribbon cable, and have a dupont connector kit for termination. My question is before i even start, will my required cable length be to long to even attempt this? The cable will need to be in the ballpark of 140 inches in length to get through all my cable chains due to the size of the printer. Can i go through the cable chains or should i just make up a temporary cable just long enough to do the tests then remove afterwards???

      the results are posted above in the screenshot. I manually saved to the config file and reuploaded to the machine. do i still need to do the M commands for that as well?

    • RE: Revo 6 PID tuning just hangs

      @Phaedrux said in Revo 6 PID tuning just hangs:

      What voltage are you reading from your power supply output? Does it have an adjustment pot?

      Just measured the voltage at the board input and its right at 12 volts, which is coming from a 1000 watt ATX power supply.

      im just spit balling here but i think the 10.5 volts has to do with the revo. I recall reading info and seeing is some videos like from thomas salander that the revo changes the voltage as it heats up to use less power as it gets near the set temp if i am remembering correctly... maybe thats why i saw the lower reading..

      @Phaedrux

      again its the 12volt version of the revo.. but since it completed the tuning i entered the results to the config file, heated up the nozzle, inserted some filament and was throwing together a quick 20mm calibration cube file with the new nozzle settings etc and while doing that i got this:

      @wingtip

      here is a screenshot from the dwc, it doesnt show the m303 command when i entered it on the panel due but the blue line indicates where the tuning command was entered... you can see that before it failed, and now it completed.... this is confusing as all hell.....

    • RE: Revo 6 PID tuning just hangs

      @Phaedrux

      lol, ive said a few times that ive verified its putting out 12 volts at the connector at the hotend when i do the pid command with a multimeter, at least till it cancels itself a minute later saying temp not rising... which makes no sense. so if its sending 12volts to the connector at the hotend, its definately got it at the mainboard, then when it cancels, it goes back to zero vdc. I will re verify though.
      Im starting to guess that you guys are gettings about as stumped as i am
      EDIT: ok i think this printer is possessed ... I went to re verify the voltages from the mainboard.

      1. placed volltmeter leads on the board terminals, reached over to the panel due and set a temp of something around 60 or 70c and it kicked on, where it wasnt kicking on before. then i looked at the voltage, it was 10.5 volts this time.

      2, i killed the temps. went to console on the panel due and entered m303 h1 s236 as before and ill be da**&&ed if it wasnt taking off and climbing, but again, showing only 10.5 volts on the meter. Will let it try to continue the tuning but im going to estimate that it will hang again on the cooldown/settling. Will let you know in a bit i guess

      @wingtip So what happens if you simply try heating the tool. i.e set the active temperature to something other than zero - say 50 deg C or so? Does it try to heat then?

      does nothing

      panel due displayed 19.5 c room temp. I put the heat gun to the nozzle area and then checked the panel due and it then showed 40.3c so the thermistor is working properly it seems.
