Hi Sam
Not too familiar with the tower foam cutters,but I would have thought that with them being identical towers and each one supports/carrys and guides the hotwire through its paces but at identicl co-ords therefore all axises motors wired in parralell with each other on the three independant axis.
I see in your screen layout that one axis is out of sync is that the way it should be?
I'm thinking if one axis lags behind this would cause a problem?
Looks like a sweet front end :)
Different X and Ys, left and right, allows for the cutting of more complex profiles.Quote:

Hi Sharbold,
Great work there, looking really good. I've not used Profili2, but heard alot of good things about it. Will it generate Gcode to drive mach3 as suggested in the title area?
Hope rckeith is reading this, perfect for the foam cutter he is building!
Hi Vic66,
Good point about tapered wings, but can the wire manage washout? Not having used foam cutters I'm trying to picture in my head how the wire would move to do that - being pulled taut limits the possibilities I think, unless you overcut into the waste using multiple passes?
For those that don't know washout is a deliberate twist (to a lower angle of attack) as the wing goes from the root (near fuselage) to the tip. This helps reduce tip stall at lower speeds on tapered wings, for a compromise at high speeds.
Not used a cnc foam cutter either, just templates and bow, I have been slowly collecting parts for one though. I would imagine you could achieve washout with multiple passes with a bit of thought, although I havent gone through that process, you could make the wing half in multiple pieces as well, my comment was in response to George's question about the axis's not being parallel but myself and ecat must have replied at about the same time.
Sounds like a wind turbine blade to me! I did consider using this method to make blades, just covering the foam in fiberglass. I was just going to carve the foam by hand though as I didn't think a CNC hot wire cutter would be up to it.Quote:

As for washout in profili you can input the amount of washout and profili will adjust the tip of the wing to add the washout.

2) how do I move both towers a fixed distance without writing G-code ?
With the standard screen set you can set a 'step' jog distance. (which i use all the time with my CNC router) Going to the setting page and clicking 'step' does not change anything and the green 'led' does not come on
Thanks.

Sir I am Inquireing re: why your mach 3 screen top has all the profili buttons and such.Quote:

Where did you buy this software?
From Mach3? or some how from Profili.
