Moin, die Schrittmotorplatinen sind übrigens fertig (und können hier bestellt werden: ). Komplette Reprap-Kits hab ich noch nicht hier - wahrscheinlich erst in den kommenden Monaten. Quotegibt es in berlin eigentlich hackspaces wo man zusammen an soetwas arbeiten könnte? Frag z.B. mal hier an, die bauen gerade einen Reprap:by joaz - Altes Forum
On the cartesian robot I'd be worried about the sagging of the steel bars. You can use thicker bars or a different shape to fix this.by joaz - General
Hi, I've got ABS filament, 3mm in stock. Colour is natural. Made in Germany. Each coil comes in about 5 kg (mostly between 100 and 500 grams more). Price per 5kg coil is 98,90 Euro. Shipping to Germany - 4,50 Euro Shipping to countries in EU - between 12 and 15 euro I accept Wire transfer and Paypal.

I can now ship out complete Stepper Motor Driver 1.2 Part Kits, including PCB and all components required to build it (except solder & tools). Price is 23,90 Euro/Set. Tell me if you need a fully or partially pre-soldered board. Currently I have - more than 100 units of bare PCB in stock - 24 units of the full kit in stock.by joaz - For Sale

try # ls -l /dev/ttyUSB* in the console. Normally it should be only one /dev/ttyUSB0 unless you have more usb <-> serial devices plugged in.by joaz - RepRap Host
Hi, I've got plenty of Stepper Motor Drivers Version 1.2 for sale. Those boards are easy to solder and the needed L297/298 chip combo is widely available in electronic shops. The PCBs itself are made in Germany, lead free and are UL listed.

I use TCST 2103 to mount on opto endstop boards (you can get those from Reichelt). You have to cut the marked trace and A to B on the pcbs.by joaz - Controllers
Ich kann die PCBs hier fertigen lassen (5 Euro / Stück, Lieferzeit 2-3 Wochen), nur 150 Stück muss ich mindestens abnehmen. So weit habe ich Interessenten für 12 Schrittmotorsteuerungen. Sobald ich Interessenten für mindestens 25 Stück habe, werde ich die Dinger machen lassen.by joaz - Altes Forum

Moin, Da manche Boards bei RRRF seit Monaten nicht lieferbar sind, hatte ich schon mal gedacht, die Platinen hier in Deutschland herstellen zu lassen. Wenn die Abnahmemenge einigermaßen stimmt, kosten die ungefähr 5-6 Euro / Stück und brauchen ca. 1-2 Wochen zur Produktion. Nur die Frage ist, welches Board lässt man produzieren? Die 1.2er Version ist einfach zu Löten und verwendet Chips, die maby joaz - Altes Forum
Hi, I'm trying to set up the arduino SNAP firmware. I previously used the stepper motor exerciser and got good results on speeds 650-900. When I upload the default configuration (except setting number of steps to 200) of the SNAP firmware, (and I try moving the motors with xyz tab on the host software) the motors run slowly with lots of vibration. Is there any way to modify the speed?by joaz - RepRap Host

Hi, I'm building my OptoEndstops V2.1 with an alternate 4-pin opto switch (TCST 2103). Some ideas for less frustration: - Cutting the trace marked "A" and brige it to "B" When supporting multiple opto switches, why not bridge it like the Half/Full switch on the stepper motor driver? This would require to bridge it for H21LOB too, but it's like 5 seconds of work to solder. - making the LEby joaz - Controllers

Sounds like really old hardware to me. Maybe try to control every part you need and hook it up onto an arduino.by joaz - Controllers
Any idea how the old ones ended up blown away? 5401 should work here, unless you have > 100V or >3A current. Just be sure to place the cathode right.by joaz - Controllers
