Well, back to square one (or two). Even if I pull the 'Extruder Speed' slider to its lowest it still moves way too fast. It's still quite powerfull and I think it has a much better grip on the filament than the screw,but if it is too fast its no good. So for now I hooked up the polymorph screwholder with the PVC filament holder and I can see at which speed it is supposed to be moving. Here isby Ron Luttik - Mechanics
Yes, it is a little gear wheel. This way I didn't need a lathe or any alien technology. On this little video clip you can see it connected directly to 5V. It goes much too fast, but I hope to compensate that in software. 4mm/sec is the aim if i'm right. (I haven't done the extruder tests with it yet and I'm not at home at the moment). The diameter of the filament I found in a local shop (HDPE) isby Ron Luttik - Mechanics
Hello to all again, Just wanted to show you what way I'm going with the pump parts. Even though I came quite close I think with making them from polymorph, but couldn't get them quite right. I ended up making a PVC version as well, which seems to work well from the first moment it was switched on. I made the polymorph version by sticking a printed version of the screw holder on the bottom of aby Ron Luttik - Mechanics
Hi, If you have another PC at hand, you might try installing all the required software on that as well. On my first PC I could perform the stepper and extruder tests, but saw loads of sendmessage errors as well. When I installed it on my laptop, the errors were gone :-) so all the errors can not be put down as 'wiring issues'. I also use a USB to Serial cable (Prolific chip) PS.

This afternoon I went to 4 different local computer shops, two more of the 'we sell everything' kind and two of the 'handy man' type looking for a 9 pin DSUB rs232 male/female cable to hook up my emerging machine. I still havent found one!!! I ended up with a female/female cable and a usb to rs232 cable which ends in a male connector. Never thought these things would become so 'rare'. I'm sure plby Ron Luttik - Controllers
Hi Joost, nice to hear from you. To keep it somewhat aligned, all the holes were drilled before the glue was put on. I also measure and drill the holes from 2 opposite sides. Checked for straight angles after every step. Your wooden brackets already tought me that proper alignment for them is quite important. (too much tension on them already bends the hollow aluminum tube that I thought of usinby Ron Luttik - Reprappers
Hello Forrest, Thanks for the kind words and the detailed explanation of the different kinds of wood. The only reason I chose the fir wood is because I just happened to bump into it and it had the right size. Someone elses was throwing it away. As you can see in the picture I made the next version from PVC as well. Glued some washers on it where the studdig will go to prevent wear and stuck someby Ron Luttik - Reprappers

Hello everybody, A couple of months ago someone wrote an article on 3d printers on a website that I frequently visit and in the replies to that article a link was mentioned to a website called www.reprap.org. I visited it, and what can I say other than that it was love at first sight. Within seconds I knew I wanted one as well. After reading more or less everything on the website for a couple oby Ron Luttik - Reprappers
