I am not entirely sure what you are doing but suspect that a servo controlled by an arduino might be the way to go. I don't think you will need a stepper motor as the forces aren't likely to be that great. You probably don't need an arduino and could do it just with switches. Hope this helps Kieran. We have finished the reprap prusa, it is working well and have printed of some of our firstby kieran-r - United Kingdom RepRap User Group
A lttile up date. We are making good progress and have started the build. The last meeting The next meeting will be at feb the 9th at the cca in the electron club. starting at 7 finishing 10ish. What we still need is here in the bill of parts. As ever all are welcome. We also realy like arduinos. kieranby kieran-r - Reprappers
Hi Brian, It usually starts around 7 and finishes around 10 ish. We are on the second floor (buzz to get in) If you need to come earlier to set up the mendel let me know, kieranwyse at hotmail dot com. The reprap is the first project that we have managed to get of the ground it is certainly my hope that there will be many more projects. We are very enthusiastic about the possibilities of the aby kieran-r - Reprappers
Just to let you know we are meeting up again next Thursday the 17th at 7ish. We are making good progress on getting the parts together. One of our group has already made one and is being a tremendous help. Thanks Joe, Yes I went with zapp automation, though I wish they had told me they were not in stock before ordering. Anyway all are welcome as usual. And it is buzz to get to the electron clubby kieran-r - Reprappers
I am looking for reprap motors. Does anyone no where we can get them on the cheep? Although any suggestions would be good. Thanks Kieran. p.s there is another meeting on the 27 of this month. Same place, same location.by kieran-r - Reprappers
This is the third meet up of the glasgow open source hardware group (goshg). We are a friendly group with and interested in building open source hardware centred round arduino board. ( An arduino is an easily programmable hardware interface capable of being the electronic brain for lots of things, robots, lightboxs, flight machines). What can be done is only limited by your imagination (well aby kieran-r - Reprappers
For those of you interested, I have book the electron club. on Location: Electron Club Date: Thursday, September 15, 2011 Time: Between 7 and 9 With the intention of starting a group to build a reprap. More information can be found here. . The electron club is in the CCA in centre of glasgow It is likely to be a RAMPS reprap. All are very welcome. p.s. there is a buzzer on theby kieran-r - Reprappers
