Good evening everybody!
I was wondering if anyone could help me out. On Mach 3 view screen my parts and signs are facing upright, however when I cut them out it is if the torch was on the backside cutting through. If that makes sense. The dross is on what should be the clean side of a sign etc. Is this a Mach 3 issue or an issue with post process and what view I draw in in fusion 360? Thank you in advance for the help!!
Sounds like the issue I was having in fusion. Go back in to fusion and watch your tool simulation, see if the torch is on the correct side. You may have to rotate the image some to actually tell
You should be able to adjust the work coordinates to flip the torch to the proper side of the drawing in Fusion without having to rotate the drawing. Look and see if the Z axis is pointing up on the proper side of the drawing.
Yes it is pointing up, and simulates correctly. It still cuts in mirror image. Anything else I can change? Maybe in mach 3? Thank you!
In my experience that normally means the wires on the x axis is flipped on the machine. Since the Crossfire comes with pre-wired ends you can simply rewire the connections. I know there’s a checkbox in mach that inverts the x axis. But I don’t have it installed yet and as such can’t point you to the screen. Hopefully I’ll get it installed this week or someone else pipes up with the answer.
Langmuir systems can you help out pleasr??
Hi @paddy2257
I’m having trouble understanding what the issue is. When you push the right arrow key, does the torch move in the positive X direction? Similarly, when you push the up arrow key does the torch move in the positive Y direction?
After doing some looking. If you need to reverse an axis in mach 3 click on Config, select Homing/limits from the drop down. In the grid click in the “Reversed” column to toggle. If I loaded my CrossFire v1.1 config properly it is setup with X and Y reversed (green check mark).
If you have tested it as Daniel has suggested and the right arrow is not a positive value. Try toggling the value.
This picture helps a lot, thanks!
When you press the up arrow key, does the gantry move in the +Y direction (away from the cable support tube?)
Yes it moves away from the support.
Did you run the break in program? And if so did it execute normally? Can you attach the cut file here? We would like to take a look at it
Double check your x and y motors are hooked up to the right connection points. I was screwing around today and swapped mine and got similar results.
Thank you! I will try that!
I tried switching the motor plug ins. When switched, pressing the up arrow made the gantry get closer to the cable holder. I switched them back.
Are the any physical dip switches I can change on the controllers them selves? I tried switching the x and y axis in the Motor/home/soft limits window in mach 3, nothing changed. Please help this is frustrating. Thanks!
Hi there,
I apologize for not addressing this more quickly. It sounds like there is some kind of issue with your motion controller that was not caught during our testing. We are going to send you a new motion control board tomorrow.
Mine does the same thing I thought it was just a setting I hadn’t found in Mach 3 yet
Hi @paddy2257
I remember seeing your machine posted on instagram and went back and looked at the picture- your cable support tube is actually on the opposite end of normal convention. Therefore, in your case, when you press the up arrow key, the gantry should move away from the cable support tube. When you press the right arrow key, the torch carriage should move toward the unsupported end of the gantry tube.
When you get a chance, please verify that the larger of the two motors is plugged into the Y axis plug on the electronics box. The smaller motor should plug into the X axis.
Now, since the TEST sign is only mirrored in one direction, i believe there is more than one issue at play. Could be that some settings in Mach3 are wrong.
That’s something I’ve been puzzling. I think the videos up on YouTube actually have the operator sitting behind the Crossfire.
If the rail with the Langmuir decal is the front and the control unit and laptop stand are mounted on the back legs at the ends of the Y-axis rail then it would seem that your normal 0,0 is the corner the laptop is on. So it’s more like you’re standing at the side so the X-axis moves to your right (toward the Langmuir decal rail) and the Y-axis move away perpendicular to you when you face the side with the 0,0 in front and to the left. So the “front” from a traditional CNC viewpoint is what looks like it’s supposed to be the side based on the decals.
It’s similar to another CNC I use - the axis directions seem odd vs the physical orientation of the machine because the gantry carriage crosses the bed back to front but that makes it harder to put things on the bed when in an enclosure so it’s typically spun round sideways which allows for easy material placement but changes the normal axis directions and I always click the wrong artow the first time 
The Shopbot has the gantry crossing the machine from the sides. On that one the X-axis goes back and forth across my front when I’m standing in front of it and the Y-axis heads away from me toward the back of the table.
Hey Daniel, I will have some time, finally to sit down and use the machine tonight. Can you call me again around 630 mountain time? Thanks!
