MemberHi, I have made a simple G-Code file with CamWorks and I am trying to run it with my CNC. The problem is that the simulation runs ok in the Chilipeppr but when I trying to run the program through the tinyG, it makes something completely different compare to the simulation.
The tinyG is a V8 with te lastest firmware installed (V0.97 440.20)
The Json server version is 1.86.The GCode File is:
Print screen of the simulation:

Thank you very much,

ModeratorSorry, aside from the current position of the spindle, I am not seeing the difference.
Can’t you describe what to look for?
November 15, 2015 at 9:06 pm #8945MemberI made two video to explain better the problem I am having. The first one is the simulation on chilipeppr. There you can see the spindle following the traces correctly.
The second video shows how the spindle is moving away and the coordinates does not match with the coordinates found in the gcode file.
Please, let me know if you need more information.
Thank you
November 15, 2015 at 9:54 pm #8946ModeratorOK, the second video is helpfull.
Does any Gcode run OK on this machine?
For example, how about the Chilipeppr logo Gcode?Can you provide a dump of your parameter set (a $$ dump)?
Meanwhile, I have flagged this for a look-see by the developers

tinyg [mm] ok>November 17, 2015 at 1:59 pm #8948ModeratorOK, I have not see a machine set up like this before, appears to be a large (in x and y and z) screw machine (or similar) based on parameters. The jerk values seem low, but that is in comparison to belt machines such as ShapeOko and Ox.
You will have to experiment with jerk settings unless you have a circle of friends who have already done that.Does Camworks give you the option to output Gcode without arcs, replacing them with short segments?(perhaps 0.01)? I believe you are subject to some arc corner case situations similar to this thread:
That is being worked, but not ready for prime time.
Also, when you are ready to try ful x-y-z- homing, read this wiki item:
You will need to change your Z axis parameter such that $ztm=0, $ztn=-150.
The tinyG homing cycle code home to 0 at top, moves down from there.November 17, 2015 at 2:46 pm #8951alden
MemberThe file contains G40, G41 and G43 commands that are not supported by TinyG. Also, the lead-in O00000 is not supported. I made an edited version that seems to run, but I’m not sure it it’s entirely correct.
https://www.dropbox.com/s/1nrlcp18aaymp6e/pieza%201%20edit-001.nc?dl=0
Can you disable cutter radius compensation and tool length offset? We actually do have tool length offset in test – but it’s the G43.1 variety, not the G43 variety that requires a tool table to be pre-set.
November 17, 2015 at 3:55 pm #8952ModeratorThanks for the hints, Alden.
DJF: You may want to review this Wiki item for more detailsNovember 17, 2015 at 4:38 pm #8954MemberI think the code needs to alarm if it finds a Gcode that’s not supported. We are working on adding more, but in the mean time…
November 27, 2015 at 5:39 pm #8991MemberIs there a post processor for the tinyG that can run on the Camworks? On the wiki page, they recommend to use the Camworks to generate de Gcode, but it seems that the post processor included by default in this program, contains more Gcodes that the tinyG can support…
November 27, 2015 at 6:33 pm #8996ModeratorYou are perhaps the first mention of program Camworks; so you are not asking any seasoned veterans here.
Can you provide a URL for the product?
Is there a particular reason you chose Camworks over other options?There is no standardized definition of the functionality of a post processor.
Waiting until the ‘post’ phase to remove unsupported Gcode commands should probably be in the core, not post phase.I will guess that, if the authors of Camworks are even aware of tinyG, the chance that they have read the wiki and accommodated what is and is not supported in tinyG is rather low.
