Hi,Could you write some more information about stepper motor that you used.I looked at primopal web page, but there is no such model as you mentioned.So if you could give some technical information like,* angle/step* dimentions (I know that nema16, but what is the length ? I guess 26mm - but could you confirm that)and maybe some electrical characteristics:bipolar, 2 phase 12V ? 0.6A ?
Hi,
The motor we used in the prototype is a Nema16 Primopal stepper motor model PHB39Y26-401.
Anyway, we are redesigning all the printer in order to improve it and solve the motor/belt resonance issues. We also want to include more functionality as PCB drilling and also the capability to print in 3D. The idea is to build a multi-functional machine which could cover all the DIY PCB fabrication need: print the PCB, drill it and also build small 3D objects like knobs or boxes. We unknow at this time if it will be feasible because the goals are very ambitious but If you are going to start the building now we recomend you wait till we finish the new proptotype which we call DiyouPCB MKII.
HiThanks for reply.Regarding DiyouPCB MKII, we won't probably wait and we start with MKI anyway :)To be honest, laser for PCB is our main goal. And one more little question, maybe in case of DiyouPCB MKII you will consider using NEMA17 ? I belive it's much more popular and easier to get.Best regards, and one more time great job !
Thanks for your support.
Yes, we are going to use Nema17 motors in MKII. We didn't want to use it for MKI because they are too powerfull for move a simple pickup. First we thought on Nema 14 but they were too expensive. Then we found tha Nema16 are more or less Nema14 size but at reasonable price so we used it.
Anyway it's very easy to modify the platic motor mounts in order to support Nema17 motors. It's the only parts you have to change and only a litle.
New machine is also focus on making PCB's but trying to solve all the issues: drilling, printing, milling, etc.

Victor
