    3D Printer problems - Monoprice/Wanhao D6

    RM-MN: I had considered just replacing everything with a standard RAMPS setup. But in addition to having to replace/reconfigure everything if I did that, the Wanhao board is a 24V board and most combo offers like what you listed are 12V boards. I ordered several replacement relays this...

    Small Weekend Projects

    I agree with you Cogsy. When I looked at the drawing all I could think of was "How's this supposed to work?" Once it was explained that became "Now that's a really neat idea." I also go along with what BaronJ is asking about restoring a post. More than once I've spent a LOT of time putting a...

    3D Printer problems - Monoprice/Wanhao D6

    That's the advantage of a 24V board over a 12V board, you're halving the amperage. So those MOSFET's that were at the upper end of their range are now operating at an more comfortable level, at least as long as THEY are rated for 24V. The Wanhao control board has got the LCD drivers, the SD...

    3D Printer problems - Monoprice/Wanhao D6

    Oh I totally agree, for most machines an 8 bit processor is quite satisfactory. I don't do any type of printing where a 32 bit processor is required. Yes, I have purchased a replacement motherboard. I got verification from Aliexpress yesterday that they had shipped, now I just have to wait...

    3D Printer problems - Monoprice/Wanhao D6

    It was static, I was the one that did the ZAPPING. Recently I had been getting shocks when I touched the metal frame of the printer, or the water faucet for that matter, so that's how I knew it was static. I'd been trying to be sure and ground myself to the frame before I touched the SD card...

    3D Printer problems - Monoprice/Wanhao D6

    I'm posting this on several forums, so for some of you this might be a repeat. I've got a Monoprice printer that is actually a re-badged Wanhao D6. I managed to kill my printer last week, I static ZAPPED it - but that's not the only problem. As I was plugging in the SD card to load a new...

    Digital Pressure Gauge

    I can think of a number of digital pressure transducers that I've used, IFM Effector comes to mind. You didn't mention give any specifics on your electrical system, but I'm pretty sure they're available in AC or DC. We use the Effector's on pneumatic transfer lines, and you can get them in...

    Just a thought, but 30 AWG grey flat cables are readily available up to 40 conductors. Strip off as many conductors as you need and mark the conductor on one side with an indelible marker. As long as you consistently number the conductors starting with the marked conductor, you can build your...

    CNCing a mini mill

    wachuko: You said "but learned afterwards that stepper motors do no like to be turned manually, reason for adding the pendant." I'm guessing that you tried moving the motor while the stepper driver was turned on and enabled, and that the motor did not want to turn? If so, the stepper driver...

    Charles: You said in Reply #112 - "more flow you need, as may well be the case, then straight vanes, roughly tangential to the eye diameter would be better". I'm going to ask stupid question, assuming a CW rotation of the impeller, how would the vanes be oriented? In my head I can see two...

    Do additive machining blunders count?

    Yeah, fortunately is was a small part and only took 15-20 minutes to print. I would have been REAL unhappy it the part took hours to print. Don

    Do additive machining blunders count?

    If additive machining, 3D printing, blunders count, then I've got one for your amusement. I was printing a replacement part for one of the R/C conversions I was working on, and the part was about 1/2mm too long. Went into the 3D CAD, shortened the part by 1/2mm, saved the file, and reprinted...

    I think we're all tool junkies. Do they have a 12 step program for that? Maybe we need to start a new forum? Hi... My name is Don and I'm a tool junky? Nahhh… Nobody would go ever to the meetings, we're all too busy in the shop. Seriously bmac2, that's some nice work on those threads...

    Resin burn out temperature

    I'd suggest that you go over to http://forums.thehomefoundry.org/index.php and ask the question on one of the forums there, maybe the Lost PLA forum? You'll probably get more responses there since they're primarily a foundry/casting forum. Don

    Cogsy: So far you bought a mill, 2 lathes, bandsaw, grinder and a 3D printer? And you've saved at least $400 in repairs? Your Return On Investment is probably a little higher than it is for the rest of us. Don

    Old School Sawmill Edger

    Wouldn't it be simpler to put in a Delrin rub block to tension the chain? That is if you've got the room? Some of the old farm equipment that my Dad had used oil soaked hard maple blocks for chain tensioners on the low speed stuff and they lasted for years. The block would eventually wear...

    Back at it. Lost pla cast iron ceramic shell

    What do you consider a blazing fast speed? I typically print at 60mm/sec, I can push it faster, but as you say, the print quality goes down. Now I'm mostly printing what are structural parts for a CNC router that's loosely based on the MPCNC. I use a 0.4mm nozzle, a 0.25mm layer height, 4...
