Re: Building Large(r) Format Printer For Ceramics

Hello and welcome Nick Powder printing has different drawbacks. Cleaning parts is inherently messy and powdered ceramics require respirators. Also parts are quite weak before firing, so cleaning them is challenging. I have yet to have made parts that stand cleaning as well as I would want to. If you...

Re: GNUOCtave Script GCode->PlanB

The double feed piston is pretty much hardcoded into Plan B. It is not individual lines of Gcode moving each piston. If I recall correctly the printer adds a layer when it detects a Z change in the positive direction. In the firmware the movement of the pistons is handles in movements, in the functi...

Standalone controller V4.0

The new year brings with it the desire to make a new controller for the inkjet. So far I have been using V3.02. This is a not released version of the controller that powers Oasis, but with some upgrades that makes it use DMA. This works well, and it has proven to be reliable, but if I want to actual...

Re: Problems with SD card

You seem to have just found the issue that has been bugging many people. Changing it to 5 will prevent an overflow from happening. I will keep this one in mind for everyone that tries the code, and will try and fix it this week in the downloads. Many thanks for pointing this out to me. My only perso...

Re: Problems with SD card

I have heard this more. Something in the past few years has broken my code, and I no longer poses the hardware to test it. The only thing that I can imagine is that something in the gcode is not being read properly, either because the gcode used is wrong, or the SD card library is. However what exac...

Re: Hacking the HP45

Hello and welcome, From what you write I will assume that you wrote the code that fires the nozzles yourself? Your printing already looks good. The problem you describe sounds very familiar. It is the problem I also have with my heads. For some reason I cannot fire all primitives on an address at th...

Re: Hacking the HP45

I can't really complain about delays given the number of posts I have made the past month. The 22.5Vμs is a number I am seeing the first time, but it does mean that I run within spec (roughly). In my experience exceeding it by a bit is not an instant disaster, though I can imagine that it will short...
