Re: Generic powder machine controller

Iota https://github.com/MatthiasWM/IotaSlicer is by no means complete, but it is an open source texture slicer. The texture functionality is currently disabled because optimizing voxel code had priority for a while, but the source code is still there. There is an improved texture slicing system in ...

Re: Generic powder machine controller

I'll make my powder printer taking a pack of ZIPed PNGs as print file, just like the current de facto LCD 3D print format. So that different slicer can be supported. Also, regarding the 3D colour model, is VRML better than OBJ? I see many colour 3D printer using VRML format. PS, the 3D print format ...

Re: Generic powder machine controller

Colour slicing is a bit complicated, simply because there are not many public available examples. The initial test of my printer will be based on single colour or manually set colour. Later development, in my option, will tweak a VRML reader and add a slicing function, for example, using the VTK pac...

Re: PowderMaker1 3DP printer

second round prototype, which features an all metal key frame and precision square rail (there is a design of the dust cover for the rail and belt, just not installed yet). This time I made it as a powder printing core. as you can see it is only the top part. Users can either put it on top of an IKE...

Re: Generic powder machine controller

PPS more words on the software and firmware This controller is designed as a complete central controller. The host software slices the 3D model into 2D raster image in the CMYK format. Standard format, like PNG, would be fine. The controller takes a ZIPed package of such print file via its high spee...

Re: Generic powder machine controller

There is a driver board as seen at the left part (black PCB), which has 5 stepper drivers, 2 DC drivers, 2 opto switch input, 3 homing switch input, power on/off button input with LED, emergency stop input, 1 extension interface containing I2C interface and LDC interface. NB. LDC is my Local Device ...

Re: Hacking cartridge HP 84/85

Hi, do you guys now know the timing/protocol of this printhead? I briefly went through this thread and found a lot of LA capture and discussion. If I missed something, please point me to the conclusion page. I'm thinking, if you don't mind, I can probably programme my ink jet controller to support t...

Re: Generic powder machine controller

Do you solder the motor drivers to your board, or do you have the headers like a RAMPS board does. The driver board is included but separated as the vertical PCB. There bunch of signals from the main board to the driver board under the FPGA control and a few other generic signals like I2C. So it is...
