those £55 usb bob's and those £5 tb6560 drivers pic for scale of them = tiny!!

Hopefully they are the size they mentioned in the advert and that isnt a surprise to you. Are you still trying to fit them into that little box you posted a while back?

Mind how you go on the voltage and current settings on those drivers.

If I can make a comment on your posts - is everything ok with this project?

There are lots of helpful souls on here who will save you wasting hard earned cash. Posting something like I want to achieve xxx and I've already bought yyy. Can any of these bits help me or do I need to revise xxx or purchase alternative yyy bits. If I've got the wrong end of the stick and things are ticking alone then apologies - not easy to tell on a forum.

Good luck with it all.

Ye and try asking the question in the Post instead of in the Thread Title.!! . . . . . . If folks are too lazy to type and ask in proper manner why would anyone bother replying.!!

No, I simply cannot fathom how to change the standard cartesian x/y positioning into H-plot gantry co-ordinates

I have discovered that it is possible to drive a H-plot gantry system with MARLIN firmware and a RAMPS 1.4 controller on an ARDUINO MEGA 2564 with a wireless receiver lcd doofer, so I have ordered all of that, BUT and I retreat 'under the bridge' awaiting your barrage due to pressing the b.i.n button before realising that I simply cannot import a graphics based .dxf or a .hpgl into the marlin/slicer pronteface stuff, as it will only take an .STL file format.

bugger I say!!

I simply want a little plasma machine to put into my car and take to the compressor/workshop/plasma machine.

I do however like the idea of sending the g-code file to the controller LCD wireless, then pressing go on the LCD.

OH - yes the idea is to make a little H-plot table in one peice, 4 motors in each corner, nema 17's - 4 drivers - one for each motor, as I have been advised it is not good practise to simply affix two motors to one drive, then two drivers to x on the bob and two to y, closed loop belt so I can pluck and tune the tension on the belt.

ALSO having trouble ordering pulleys, I now know I want HTD 5m 9mm belted pulleys in 20 tooths - worked that one out after buying a fair few......... 360 divided by 200 steps = 1.8, simply times by 20 teeth = 36 again!!!

anyways the problems I am having is vendors list them for example '5mm pilot bore' so I simply assumed they were bored all the way through at 5mm - plus the pics show them to be already grub screwed, of which they are not, they are simply drilled a few mm deep at 5mm - - pilot bore.

so what I want now is four 20 toothen HTD pulleys 5mm pitched 9mm belt, bored for 5mm with grub screws.
also want the above in 6.35mm
Is there anyone who can help me bore them and drill and tap them for me? as I don't have a lathe

also want the above in 25mm but maybe 8mm bore, I don't know yet

t seems they simply do not make a 20 toothen 8m HTD pulley 20mm wide.
