I recently purchased a 1013 and can't find a post processor in PhotoVCarve that can create a file to run through i-Picture to give the necessary GEE file to run the machine properly. The Larken(mm).nc run through iPic seem to track to scale but won't spin the tool. The only way I can make it work right is to import the .pvc file into VCarve Pro and output it as a .crv file then through i-Pic to get a GEE file. Is there a better processing tool available?

Great! Please tell me where I can find it, thanks.

Thanks. OK, iCarverXinch.pp works with the 1013 Process but the Border still seems to move the spindal in mm rather than in inches (the same as the iCarve inch pp in VCarvePro).
A couple of other concerns come to mind when looking at some of the posts which do not seem to generate solutions:
1) Is there a way to slow down movement in the Y axis which shakes the machine enough to rock and roll on the bench, other than to use the slow feature?
2) Is there a pp available to switch the X & Y axis movement so longer items like signs can be used lengthwise in the Y plain - other than rotating the drawing, ie in VCurvePro where it is easy to rotate the vectors but not the bitmap PhotoVCarve imports?
Thanks.

I use the setting "F-250" here is a sample from one of my files:
G90G17G71
G0X0.00Y0.00Z20.32S12000M3
G0X26.08Y75.63Z5.08
G1Z-0.91F-250.0
G1X26.18Y75.42
Notice the F-250 that stands for feed rate code in photovcarve, actually it's more than that but its the only change for feed rate the post processor puts in the code so you can just add it to your nc file.
I make multiple cuts so I don't dig in because of the speed and that setting is in the software for the max depth of a pass.
Since this machine has screws on two axis's and a gear drive on one you can end up setting the feed rate so slow that its normal for the Y but painfully slow on the other two x and z.
You can increase or decrease that 250 setting and play around with your speed.

The inch pp can be fixed and I have found the error but I never used it because I just use the mm pp.
Also when I need to rotate a bitmap before working with it I use a program called IrfanView mainly because it loads fast and has lots of options like auto cropping the borders to the edge of a picture and fast rotating a picture.
If you own PhotoVcarve you should check out the free program they give called 3d machinist it's not listed on the site but you can find out how to get it in the forums.

Thanks for the advice. Your F250 note is interesting and I find it to be set by the tool feed rate and that is a satisfactory method for slowing everything down. I never wanted to get into the code, but I found it quite simple and was able to modify the icarver pp to flip the X and Y axis in order to draft long items like signs with x= length and y=width to send to the machine as X= width and -Y= length. I find it best to set the origin to the top right. I would attach the files if I had permission to add them.

Well that sounds interesting you may have talked me into going back to that post guide and checking it out thanks.
I think I would name that file something that lets you know its not a regular post p file so you don't turn stuff you didn't want turned.

It's been a while but the problem as I remember it with the post p inch file was a setting that set metric and standard one was 1.4 and the other was 1.3 and I think they are both set at 1.3.
I would have to go back and read the manual again to make sure which was which.

I called the new file "iCarverX2Y inch.pp" since it swaps the X and Y axis, and shows up as "iCarverX2Y inch (*.nc)" in the VC menus. The same pp revisions work in both PhotoVCarve and VCarve Pro. Here are the simple line changes used, all in "Formating for variables":
VAR X_POSITION = [Y|C|Y|1.3]
VAR Y_POSITION = [X|C|X|1.3|-1]
VAR X_HOME_POSITION = [YH|A|Y|1.3]
VAR Y_HOME_POSITION = [XH|A|X|1.3|-1]
The 1.3 etc. is just code for the number of digits after the decimal. As they are for the 1013, the imperial positions are shown to 3 decimal places (ie x.001 inch) and the metric version is shown to 2 decimal places (ie. x.00 mm).

:'(Not that great! Back at it again though:
I have measured X and Y speed time in milling a profile (in air) inside a 10 inch square and found that the Y speed rate is always about 4 times faster than the X speed rate and is about 2.5 times the set tool speed rate. I modified the nc pp code to multiply the F rate by 0.4 and other constants and found that the F number produced by the nc and gee code is correct but when running the machine it makes no difference to the speed! There must be some other variable controlling the feed rate?
How did you implement your F-250 factor to control the rate?
Why cant Oliver give us firmware to work correctly with g code and specified tool rates that will produce equal X and Y rates??
On top of it all, the spindle dropped about 3/16 inch ruining a job and now the spindle lock wont work. There are some posts on this but without a solution to fix it.
I think it is time to return the unit.

Donk, please call 800-559-5065. There is a newer Firmware and HMI file for machines that are having difficulty. Regarding the spindle drop, try putting a block of wood under the spindle and tapping it up into place. If that doesn't work, there is a modification to install set screws to hold it into place.

Donk, I never had the spindle drop problem I guess I've been lucky but that problem sounds a lot like a big drill press and to make those spindles stay up you need to clean the shafts with something like acetone.
As far as the speed of the machine goes you have two different gear ratio's on this machine so you can never get the thee same also I slowed my machine down with the speed setting in cut2d's tool setup you should be able to find that setting in photovcave.
I just looked at my photoVcarve and yes in the but setup you have a speed setting and I think I set mine for 10 instead of 100 play with it and see what you get.
The F-250 setting was in the post file to compliment the other setting.
What you have to shoot for is a compromise between how deep your cut is and the speed.
I never had to slow my machine down using photoVcarve I do know a few tricks with that program to make your pictures come out wayyyyy better like making your line spacing 15%.
Hope this helps
P.S.
I went through a lot of wood while learning this machine, it seemed hard at first then it got easy. just sayen.
