The nearest I could find doesn't quite meet your spec - the duet controller can control 4 steppers (2.4A each) with on board drivers and 5 more...
Good to see things are now running smoothly. EMI from mains cables can run to 100's of volts though. The likelyhood of it damaging your...
I don't know a great deal about the stepcraft, but I notice they mention a Dremel or Proxxon as the spindle. These are basically engraving tools...
Another possibility is EMI - are your mains wires well away from any low voltage cables? You often get away with wires crossing, but parallel to...
[ATTACH] As it will be at least 12 hours before I can get to some cad software I've had to resort to using a carbon isomer encased in a ligneous...
Even further thought - to eliminate slippage you could use a toothed belt and a toothed driving pulley (I think Openbuilds could supply the parts...
I'm on my phone at the moment so can't draw this, but anyone who has assembled /disassembled a drawing board with a parallel motion will recognise...
Very true - a worm gear would be immovable under that load. Alex.
You might also need a catch to hold it in the raised position - I would research how push-to-catch/push-to-release catches work (as often used on...
I could try to fill that space (too many hobbies) Alex :ROFL::ROFL::ROFL:
Hi Shawn, very nice build, but what I'm really, really envious about is that workshop! Alex. :thumbsup::thumbsup:
Leadscrew machine is best for aluminium (higher torque), belt drive is better for plastic (higher feed rates). Having said that you can cut...
Your warning has told you the answer @Colin Mccourt - there is a dodgy connection to your X axis stepper - check plugs and then (dare I say it)...
Sphinx 1050 with power supply, wiring kit, 4 steppers and controller (Xpro V4 - blackbox is same price) is 1532 dollars. Alex.
Regarding the cooling fan, I tend to have a vac nozzle really close to the bit - sucking cold air past it - same effect. Alex. :cool:
I haven't worked American (black) walnut and only used hand tools on European walnut although I believe they are very similar to work. How they...
Can't answer that @sharmstr, but from my experience of machining mahogany (which they give figures for) I would say that the term "mahogany"...
I just did the imperial/metric conversion sums on the chart from carbide which was for a 1/4" bit, but I don't think it even said what sort of...
As you have 1/4" and 1/8" collets I would suggest you look for 1/8" shank bits on E-bay. Do they need to be drill bits? Most people use router...
And if you are going smaller than 1/8" a good chance of breaking the bit - especially if it's carbide. Alex. :(
