SmoothStepper USB / What breakout board to use with Smoothstepper?

« on: October 13, 2010, 09:59:51 AM »

I'm considering Smoothstepper for laptop use on a small desktop PCB/engraver, what do you guys use as breakouts?

Hi,

Nice product!
This is mostly a hobbyist forum so if you publish data (supply voltage, current, pinout etc.) and if possible price + shipping cost to europe and USA you will get more customers!

Inverters (VFDs) are notorious for sending out interference, the better ones comes with filters to take away the interference. Check your grounding like Dan said and use shielded cabe between the inverter and the motor.

wow, that was a good read, your site ate my friday evening!
I am especially impressed by the 4:th axle with the homemade worm gear!!!

Hey, I have one of those! I have just tried it out on my workbench but it runs very quiet.

They are not only machined, the whole thing was put in a giant oven at Rolls Royce/Kamewa plant in Sweden, I have a friend that worked there building tools and fixtures for water jet propulsion eh... stuff! Lucked out on that one, they put it in with some giant machine parts for free!
I am not a machinist och mechanical engineer (my field is electronics) but I am learning with the help of forums like this and very patient friends...

I got some new energy now! Do you have a link to mor details about your machine, motors, drivers etc? This forum is big!

Hi,

Great project, very inspiring!
I have a machine in the making that is surprisingly similar to your machine!

I have a Synrad 48-1 (16W) that I am going to fit on it and regarding the tickle electronics I solved that by asking a friend to program an 8 pin PIC microcontroller to take mach step + dir (or step + laser on), generating the tickle and adding that to the step-pulses. There is also a manual mode where a button sets laser on and a pot or voltage 0-5V sets the laser power for testing or other applications.
It worked right away but might need som tweaking and input from other users to be perfect. My friend also made a pcb for it but I have it on protoboard for now. Drop me a PM if you are interested in testing it, I have much work ahead until it's laser time!

I have been building my machine very slowly for a few years but life, work and kids seem to get in the way all the time...
I'll make a thread about it when I get a little further off the ground so to speak!

This is a pic from february 2008 and not much progress has been made since!


This is my laser with improvised cutting nozzle with 12diameter, 50mm focus lens. The lens is far to close to the laser for optimal cutting cuality but its ok for experimentation.


(sorry for the threadjack, I just saw some (infrared) light in the end of my tunnel!)
