I have some of this under my bed (a bit over kill no doubt) .. Cut a couple of strips to fit on top of the extrusions maybe?by Pippy - General
Well, I have one of these ( DPS-750RB ), it takes a few more seconds than a couple to discharge and turn off (if the bed isn't powered) than the one you have, so I wouldn't worry about it .. it's totally normal. Up to 57Amps these are, very tiny for what they can give, very nicely made, the QC on them is nice. Amazing what you get for around £14 inc postage. I also have the typical chinese Pby Pippy - General

Have you tried using the new user thermistor option in Marlin 2 ? If you FIRST set the 25C point OK (measure the thermistor resistance at 25C and enter that value), then you can adjust the beta value to compensate and adjust out the higher temperature inaccuracies.by Pippy - Firmware - Marlin
You have some kind of 350Hz'ish pick up on your ADC values leadinglights (going by your graph) which you for sure has noticed. Wonder what that is ? If your piezo sensor leads aren't a twisted pair, then maybe try twisting them (or use screened lead), that super-imposed HF should then go away I'd have thought. Anyway, good work, thank you for sharing ! Am just working out what the best way isby Pippy - General
Yes my weller solderings work like that leadinglights. I guess it's finding a magnet that regains it's magnetism when it cools.by Pippy - General
Quotepiper3d Quotethe_digital_dentist The biggest problem I found was that it sucks moisture out of the air. You may want to look at "FilaDry" device. It promises to dry filament as it moves it from the spool to the extruder. It was shown at MRRF and it was feeding the filament from the spool drawn in the aquarium tank full of water to the extruder. I'd maybe not ..

Maybe use some aluminium solder as the thermal fuse, run it along the side of the heat block simply stuck down with thermal adhesive tape ? You can get it with set melting points of 220C'ish to 500C'ish.by Pippy - General
It's a good idea! You can get up to 300C in a typical thermal fuse case style. As leadinglights said, you'd need to electrically insulate it from the heat block (the case is connected to one of the leads), but easily screwed to the side of a heat block with a little aluminium square block drilled with a hole for the fuse I should think, or just clamped to the heat block with a strip of aluminiuby Pippy - General
There is the TEMP_STAT_LEDS built-in option if you wanted.by Pippy - Firmware - Marlin
Quoteobelisk79 So, being a user of vslot+wheels for linear motion for 3 years now, I fail to see the reason for all the negative references to it. I'm certainly not against v-slot and wheels obelisk, infact, I like the idea, it's a good cheaper solution for the home printer. Not everyone wants to or has a need to spend $1000+ to satisfy their need for stiffer bigger whatevers. I guess with anyby Pippy - General
QuoteLoboCNC Plastic or steel rollers on extruded aluminum is never going to produce a great linear slide. The main problem with linear bearing on round rods is that people aren't using ground and hardened rods, which is a must. I guess they'll be very much like v-slot and wheels.by Pippy - General
I like itby Pippy - CNC Routers, Mills, and Hybrid RepRapping
Yes interesting. You'll have to show us the whole printer in your next video. What printer controller board & stepper drivers are you using I wonder ?by Pippy - CNC Routers, Mills, and Hybrid RepRapping
I wonder which power supply it is you have ?by Pippy - General
Very nice ! 3030 version would be nice too.by Pippy - General
You've certainly stepped on a few toes around here piper3D lol. Well done ! Anyone who enjoys letting their imagination and design ideas out into the open is fine by not just me, we like what you've done piper3D, it prints, which means yes ! and at a price that makes a lot more sense to the home user.

When the stepper starts doing that, maybe try holding the filament yourself by the extruder, release the extruder wheel pressure on the filament, and slowly push the filament through with your fingers, just to see if the filament path is not getting stuck somehow. If not, then when it does that, just release the extruder's filament wheel pressure again and see if the stepper starts rotating normby Pippy - RAMPS Electronics
It's not a transformer, it's just a smoothing/noise reduction inductor. The transformer has yellow tape around the coils.by Pippy - General

5.5V ? I didn't know the vref's could go that high ?? You should normally have them around 0.5V to 1V'ish (depends what stepper current you want).by Pippy - RAMPS Electronics
mmm that's totally fixable. Looks like the wire has been cut too short for any solder to hold it in place. I'd cut a short piece of solid core copper mains cable, solder that through the right hole and onto the wire on the inductor. Unless you have have solid copper wire laying around to use. You might need to scrape a bit more insulation off that loose wire first to get a good soldered joint,by Pippy - General

What do you mean by 100 ohm sensor resistances on your A4899's ? Hoping you don't mean the current sense resistors are 100 ohm each ?by Pippy - Firmware - Marlin
24V for the motors is MUCH better. But you might want to use hybrid threshold for the TMC2130's to work in both modes (speed dependent), but that will need you to discover usable threshold values for switching between stealthchop and spreadcycle. Doesn't a delta need a 32-bit board for the stepping and kinematic calculations etc to keep up ?by Pippy - Firmware - Marlin
I did wonder. Is that the Loctite 5399 ?by Pippy - CoreXY Machines
I can't help with the RADDS board but the current software serial driver code for talking to the TMC2208's can operate with just a single pin (half duplex mode) rather than seperate TxD and RxD pins, so that means you don't need the TxD pin. Once you find out which pins you want to use, just specify the same pin for TxD and RxD for each TMC2208. You'll need a 1k or so pull-up resistor from eachby Pippy - Firmware - Marlin
