If I remember correctly, he determined his breakout board was faulty and was not sending the change direction signal to the driver. Check your wire connections first though.

It will work with Z, A, B, C or F.

Not at this time will PEP generate the M10/M11 commands.

TTL is a type of modulation input which is 0v is laser off and 5v is laser on so you can pulse the laser. J-tech's TTL laser driver will also except a 5v max PWM signal to turn the laser on and off (pulse) at a very fast frequency.

The info is on our web site about the Variable Feed Rate in PDF links in the PEP page. You can also download the Demo from there. http://www.picengrave.com/PicEngraver%20Pro%204%20+%20Laser.htm

There is a fan avaliable for the LD heat sink on J-Tech's web site. Not only will it cool the heat sink, it will also blow the smoke away when engraving. It will also help to keep contaminates from collecting on the lens.  http://jtechphotonics.com/?product_cat=accessories

If you do use the VFR code, do not set the driver at no more then 1.7a. That is the maximum recommended amp input for the 9mm Nichia 445nm LD.

Your step-over (Pixel Resolution in PicEngrave) for raster engraving images should be based on your focal point burn line. If this is set too small, overlapping of the burn lines will occur and detail will be lost and if it's set to high, un-burn lines will appear in your engraving. The smaller the focal point is, the finer image reproduction detail that can be achieved and gives a more intense burning power so you can engrave at a higher feedrate.

As Tweakie stated, you can set to a different axis letter other then Z and use another axis direction pin to TTL engrave using a Dithered image. PEP will generate Dithered images and allows A,B, & C axis letters also. There is another option in PEP that will allow you to use a Variable Feedrate (X,Y & F) to get shading using a TTL or CW Laser Diode drivers, but this requires a very good heat sink on your Laser Diode because it will run at full power for long periods of time. However, it does give excellent 8bit shading results.

Thanks Ian,

I don't know what issues everyone is talking about with Mach3.  My system is simple and very reliable using XP with a Lava dual PP and I don't seem to have any issues. I, myself, will never upgrade to Mach4. If it's not broke, don't........

Ian,

I'm interested, but my probe crunching issues went away when I quit using the probing routine that comes with Mach3 and started using your 2.5D edge and 3D probing routine and the probing options in MachStdMill Professional Edition. I remember you were working on a new Deluxe version, so did you ever finish it? I sure would be interested in trying that also.

Thanks. Jeff

Mike,

correction in my first post. Use Angular for the rotary instead of Linear.

How about if I just attach my spindle rotary Mach Profile in a PM for you to try? If that will that work for you, then send me a PM.

Digging through menus and typing here or explaining on the phone could get very time consuming. I can only assume your screws are the same ratios and you may have to convert/set from inch units if you use metric instead. I know the Z axis steps per. will not be the same because I changed mine to a 2-1 ratio for rotating a shaft encoder also from the stepper motor to the Z axis screw for laser diode engraving. I don't use notepad as an editor so you will have to change that in Gen. Conf. also. It should get you running, but you may have to make some changes.
