Any time you spend learning Dynapath Conversational would be directly applicable and useful to your gcode skills. The languages are not all that different. If you learn one, it would probably take...

Unless you are doing really big files, 1GB should be fine. I've never run into a limit running Mach3 on XP with 1GB... of course 2GB us probably better. It cost like $10 to upgrade my laptop to...

Laptop parallel port should work just fine. Even at 3V output, that is above the switching threshold for TTL, 74HCT, and even 74C logic. There might be some devices with issues, but I have never...

Yeah, laptops can have issues with things like auto-power/clock-reduce, parallel ports, etc. I found a post on a forum that mentioned a guy used a Compaq EVO N610 with Mach3 and it worked just...

I run my mill and laser cutter off of some Compaq EVO laptops (WIN XP and Mach3). I bought 5 of the laptops off of Ebay for $125 total, shipped, loaded with legit OS's. Microsoft Office, and some...

One of the first places I looked... there was a likely looking document, but it was only a post-processor script. I did not find anything else... got a link?

CNGBRICK has been a great help in...

Many thanks, the devil is in the details...

The most crtiaical / common events that I would need some info on are the (0) - rapid, (1)-cutting, and (2) arc commands. Also the (8) dwell command.

And what is (5)? I've never seen even a...

All of them! My goal is to feed it any valid CNC program and be able to convert it into something that would be able to run on any of the supported machine types or to one of the cad/image file...

I have written a program that can convert between the gcode dialects of over 75 different controls. It can also handle several image/cad file formats and convert them to/from each other and/or...

I never bought the pendant for my controller...

Did you buy the pendant from the same seller as the board? Many sellers have warnings in their listings that the pendants are not compatible with all boards.

You need a spindle with a position feedback sensor to do what you want to do. Your example will fail because it can not account for the spindle acceleration / deceleration time.

Also look into...

One (very) long shot to try is so put the G98 and G81... on separate lines. I had a similar problem long ago, and for some unknown reason that fixed it.

Is that a metric ton or imperial ton? :rolleyes:

VERY few machines let you do an oval by scaling one axis. Most machines take either the smallest or largest axis scale factor and apply it to all axes.

WHen you say it only loses steps on the Y axis, do you mean the Y axis channel marked on the controller board or the physical Y axis on the machine?

Have you tried reducing the maximum allowed...

Swap your X and Y axis stepper motors. If the problem moves then there is an issue with that stepper motor working with your board.

Sure it is... for instance in C the function is atan2(a,b)


Pascal, how quaint! Even its creator has disavowed all knowledge of and responsibility for that horrid language...


As far a CNC...

There are many different controllers that work in many different ways. Common ones are:

a) IJK are always incremental (most common)
b) IJK are absolute in G90 and incremental in G91 (actually...

0.44A/phase is VERY low (like suitable for toys). You are probably not going to get much power/speed out of those. Most serious (but small) steppers are more likely in the 2.5A-3.5A range.

I am using them on a MAXNC15 pile 'o crap mill. It has 1/4-20 acme lead screws and I can drive it at a whopping 12 (count 'em - 12) inches per minute with the stock steppers on 28V. With some...

Yes, that would definitely be the best place for them (but I bet those '17s make dandy fuses). I put the zeners in the opto sockets since that was easiest to do when I was testing the mods. It...

Instead of just bypassing the optos with a jumper, also install a zener diode (5.6V - from the old opto input to ground) This will provide some protection against disaster without slowing down the...

Sorry... G43 was a typo... meant G41.

I've run into the cutter diameter vs the inside circle radius issue with tool compensation a couple of times. I don't remember which controls were messing...

If you are using the cutter radius compensation commands (G42/G43) to do the offsetting, a lot of controllers don't like it when your tool diameter (6 mm) exceeds the radius of the circle that you...

I don't think the Oi series supports params 6031/6032. They are not in my Oi parameter manual.

I have seen people key a program to a particular machine by putting some uniquely identifying info...

I am writing a sort of universal CNC post processor type of program. With the 840C, etc controls you specify axes by number in several of the "@" commands. The standard axis numbers do not appear...

Also be aware that although G18 is often called and documented as the XZ plane it is actually the ZX plane (on almost all controls). It can be very confusing. Test it out before cutting anything...

Try reversing the polarity of the step pulse in you configuration. That may give you the proper setup/hold time in relation to the direction signal. Depending on how you did the mod, that may have...
