Got more parts today so I finally have connectors, USB and SD-Card mounted – lack Ethernet yet + discovered that the PSRAM has a more narrow footprint than I used. Not sure I am bothered with mounting PSRAM on this version because strapping another nCS will be difficult – one nice thing with narrow footprint…
I bought a Monster8 board some time ago because I needed a control system with 5-7 RAMP’s for my PnP machine. I got a bit surpriced that no-one else uses this for OpenPnP, so I might be up for a surprice. But, lets get cracking. This board is very powerfully and much cheaper than the…
I am building a PnP Machine based on lumenPnP (an OpenPnP) variant, but as I lack many of the specialized parts they use I have to make changes. This has been a great project as it forced me to lern how a PnP machine works and what challenges it included. As I upgraded to version…
I borrowed the design from LumenPnP (an OpenPnP variant), but I am honestly not impressed with their mechanical skills, so I re-designed the head. Firstly I needed a different end-sensor and added one on each side. But, the major issue was the blue belt holder that difficult to print and would not fir the belt…
Finally got around to design holders for my Nema8 Nozzle head + I added a damper between the Nema17 and the head to reduce noise. I need to design tank-belt holders and I can start assembling pneumatic tubes and control system as I should have all parts by now. I used FreeCAD to design these…
I ordered CNC belt driver wheels a bit quick and realized just now that their hold is 6mm while the shafts on my steppers are 5mm. The extra 1mm meakes a “hump” as the belt move and the combination is not a nice, smooth belt drive – so new belt wheels have been ordered. I…
This picture (above) show the PnP Nozzle head. (1) A Nuki 506 Noozle, but I have several noozles. (2) A noozle holder. (3) A Nema8 hallow shaft Stepper and (4) And adapter for rotating hallow shaft to vacum tube. These are some of the most expensive parts of the PnP design. I have received 501…
This is an early draft of a new, scalable control system for the PnP and later CNC machines. It is based on my own PLC system. I will re-use an older 3D Print control system or even get a OpenPnP control system in the first place, but I want to replace it with my own…
This picture is from LumenPnP (Opulo) that I use as base and show that they already have corrected the weak mechanical leg, but obviously not updated the open source drawing – or I must have downloaded the wrong ones 🙁 Never mind – I have glued the part that broke and they will do for…
The red arrow show both the slice/print direction I used and where this part broke off. This is a corner peace and I needed to print it in two parts – that worked perfectly, but as I put the 2020 frame parts in I also accidentally dropped it to the ground and the piece broke.…
