General Mach Discussion / Re: retrofit - steppers or servos?

« on: October 04, 2007, 12:57:46 PM »

The power to drive the gecko's doesn't need to be regulated.  Skip the regulators,  all you need is to determine the outputs on your transformer (you will want the voltage in the range you are looking for & current capacity), run that to your rectifier, put your output across large filtering capacitors and feed your Gecko's.  You will need a regulated 5volts for signal/controls, you may be able to pick that up from the other multi-taps on the transformer and put that through a 5 v regulator.

No luck finding a schematic on the driver boards?

Maybe a high quality picture of one both sides, good enough resolution to make out the chip numbers and wire traces, would enable someone to determine if their is a point to inject a step /direction signal into it without buying a bunch of new hardware.

I would be willing to take a look.

Mt Man,

What would be nice is if there were a tutor near you.  So much more can be done in 1 hr of teaching than a month of emailing.  That might be a good idea for this Forum,  maybe in the support section, way down at the bottom put in a tutor req. or place people can offer to help those near by.

Mike,

When you go to load screens, select the file types as turn sets   they have the file extension of lathe.lset or 1024.lset

Are you seeing the wizard from the wizard menu selection?

I think the only thing wrong is you don't go to view, you go to wizards and they should show up there.

you need to put them in a new folder under mach3\turnaddons\my turn

put the turning.set and turning.set.def here

Then make a subfolder in the folder my turn, called bitmaps, this is where the bitmaps are put.

Then when you run mach3 don't use view, just go to wizards and it will show up in the list there.

Cool looking plaque, I don't suppose you could share the gcode for me to try?

Mike,

It is in the chat forums, go towards the bottom of the topics, there is a downloads section, then drill down to the others section and it is in a topic extra turn wizards.

Mike,

I would be glad to check them. 

Check out the additional wizards I made in the downloads section.  They are an ID groove, an end groove, some tapers if you need to taper up to a face or don't know the angle just start and end points, and an experimental parabola.

Another way to really understand how the wizards work is if you have a little basic programming experience or knowledge and some gcode understanding, use the screen designer to open up the wizards and dig down into the basic code that is used to generate the Gcode from your inputs.  It can be a great learning tool on how these work.

That is sort of correct. 
The clearance is for tool clearance,  so if you set in 1" for x start and .5 for x finish, and lets say 0 for z start and -1" for z end.  say .005 for rough cut and .01 for clearance, and finish cut of .002
The first move will go to z start +.01 and x start +.01, this will be a rapid move. 
Then it will move in to x - rough cut, or .995
then it will move z to z end - finish cut or - .998
then it will move x to x start - rough cut and z to z end + clearance rapid move.

all the clearance is for is to ensure the tooltip is well clear of the work when doing the rapids back to the start point of your next cut, it will clear the workpiece in both the x & z.
The clearance will not affect the final end cuts or final dimensions,  the finish cut will cut it to what ever you put into your z end and x end.

If you go to the downloads section you will find some more turn wizards that I made to do other cuts not found in the standard turn wizards.

I wouldn't hold my breath for the tutorials,  they are busy making new program functions.

Mike,

The clearance is how far away from the stock you want to pull out to when doing your rapids.
