Re: Hot end jamming fix
Touch wood... but I think that was it. The printer has been running solidly for several days straight on a bunch of different prints - torsos, terminator head, component drawers, bits for itself etc etc and not a single nozzle jam-type issue... I had to re-add some part cooling fans (PLA)... I guess...

Re: Hot end jamming fix
Further to my list... I was getting jams again so have ordered, as a backup to the J-Head mk5b, an E3D mk5 3mmm bowden hotend, but the day after that, my samples of some custom PTFE tubing arrived... I got 5.0mmOD with 3.0mmID and some 5.0mmOD with 3.2mmID (all tolerances assumed to be +/-0.1mm). Th...

Re: Smoothie-ware
At work we use the ST Microelectronics M4 ARM. Specifically the STM32F405RGT6. We initially looked at the ARM that is used in the Smoothie board, however ST were upgradable, pin compatible and cheaper. We also found loads of bugs in the silicon around DMA and ADC timings in the LPxxxxx. With this bi...

Re: Problem with Printer_Radius!
Hi,
You might want to read my "hello from NZ" post in the welcome new member section.
I detail exactly what you need to do to set printer radius.

Re: XL delta build
Hi, I'd recommend you do not use those style resistors across the mains. They are notorious for failing 'short to case' which, depending on the failure location in the series string, will still likely cause excessive dissipation in both the wires and the non-failed resistors. You may well end up wit...

Re: Aluminium Clad PCB Heated Bed
I think the job was something like NZD600 Total, so maybe NZD200-300 but I had work stuff to make also, so it cost me nothing. You could also get a 4L FR4 board from a prototype fab house in China and do much the same, just balance copper on each of the layers and it should be pretty rigid and shoul...

Aluminium Clad PCB Heated Bed
I just thought I'd share my heated bed design. We use 1.6mm Aluminium clad PCB material for work reasonably often so when it came time to run another design, I added a heat bed to the design panel. (I actually added one for my Rostock Mini and one for the Tantillus that others at work have built). I...

Re: Print Head falls down when off
Depends on the output drive topology - most MOSFET output transistors have a body diode inherently. For a normal 4-wire stepper, the H bridges should enable full 4 quadrant operation and each FET should have this inherent diode. These diodes are biased towards the supply so when the motors are moved...

Re: Hot end jamming fix
I recently had many of the same problems with the hot end jamming and/or the extruder (EZstruder) slipping. There were multiple causes of slippage: 1) print head too close to the bed As noted elsewhere on this forum, if there isn't room for the filament to come out, the internal pressures in the noz...

Re: Hello from New Zealand
You should be able to get them from any mechanical engineering type shops - I'm not familiar with who in the US, but McMaster-Carr (who I've seen mentioned frequently) probably have them. Just looked, yes they stock them - Measuring and Inspection section - Micrometers - Starrett Micrometer heads. J...

Re: Hello from New Zealand
haha thanks!
I can set pretty much exactly the same amount of bite of the nozzle tip onto a slip of paper at each of the tower positions.
Worked as well as I'd hoped.

Re: Hello from New Zealand
The micrometers are off some XYZ linear stages which we have a ton of after automating some jigs. I drilled a (just) clearance hole in the base plate and a side locking screw (and clearance bore to get the M3 tap in) in the end of the plate, one on each of the three long sides of the Rostock Mini ba...

Hello from New Zealand
Hi everyone, My name is Jared, and I'm a senior electronics engineer for a company that makes touchscreens for many of the worlds PC manufacturers. Recently though I have been building my first 3D printer - A Rostock Mini. It has provided a welcome distraction from work! Very quickly, its a standard...
