Re: Hacking the HP45

Hello and welcome Jacky, The V3.02 board needs a Teensy 3.2. A 4.0 will not work for several reasons. The non tolerance to 5V is the smallest of the issues. The extra pins of the 4.0 are broken out wrong to be used on V3.02 controller and the controller uses functions (specific DMA pins) that are no...

Re: Standalone controller V4.0

There is one nozzle wrong that I need to fix. Otherwise it seems good. I have just received the new PCB's that should work properly. The controller does not use SPI to parallel out. I think I created confusion somewhere. It does not use SPI to drive the outputs (I did try). The controller at some po...

Re: Grain micro powder printer

I did have the machine running. I would have to dig around to find video's. It did give me a lot of good new features on the inkjet side, but Grain itself was a bit of a disaster. Pistons constantly jammed and the machine ran poorly. I still like the concept, but I would make a V2 if I were serious....

Re: Standalone controller V4.0

Printing quality is better than the last shown images. In the images the encoder was not calibrated. Printing quality is the same as with any other printer. SPI is not yet implemented. I still do not have that much experience with SPI, so any protocol I would write would be written with no eye on ac...

Re: GlaDOS lamp

Cool to hear you giving the Glados a try. I did say the 100-200h time. Nowadays it might be less, it was 6 years ago. I think I printed at something like 3 perimeters, 20% infill and 0.2mm layer heights. This is what I would do these days at least. Some parts do have challenging supports. Something ...

Re: Standalone controller V4.0

Commissioning the controller took way longer than expected. I had a few problems. Wrong trace.jpg PXL_20210314_100448831.jpg The first is that some unknown person decided that one trace did not need to be connected. It was easily fixed, but it does already mean that my prototype boards will need an ...

Re: Standalone controller V4.0

I now have an assembled V4.00 board. The boards arrived yesterday and I couldn't help myself. Here are a few of the changes compared to V3.02. It is finally on a single PCB. The 2 boards were starting to give me a headache. It runs on a Teensy 3.5. This gives it more RAM, more pins, and an SD card s...

Re: New layer gantry exceeds end stops

Changing the kinematics will probably be the cause of the issues. This code is not really designed for easy kinematics changes. Step X and Step Y do not really handle the kinematics, they handle the movement and position of the motors for X and Y. This is why you do not see a compensation for the ac...

Re: New layer gantry exceeds end stops

The movement of the gantry out of the way is handled in the firmware, not in the Gcode. There is not really any data in the gcode which moves the gantry. You modified this firmware to handle a single feed piston? Can you either share what you changed or attach your current firmware? I can then take ...
