Some time ago you may remember me excitingly posting about getting my hands on one of the first Nfire1 3D printers and talking about the assembly. You may have wondered why I never posted a follow up to this. Sadly after a bit of back and forth with Alex and a lot of swapping components for testing I was never able to get the printer working. The three motors on the axis work fine, but something is not quite right with the control of the extruder motor, so no filament ever feeds through. There are definite downsides to getting your hands on a first run of a new product.
I am able to manually feed the print head (shoving filament down the feeder tube) but that is not consistent enough to get it to work well at all. You can see my most recent attempt in the picture, which was supposed to be a small print of the Maker Faire Robot From the electronics point of view the only part that I have not actually replace/swapped out is the RAMPS board and the Arduino Mega.
With so many projects on the go at the time and as I am always learning as I go, I shelved the printer until I felt more confident in working out a solution, but I recently found that I could pick up a RAMPS board for about £5, so I am going to try and replace it in the next month or so.
