Greetings . So excuse my ignorance but I just set up my Crossfire 2x2 plasma table. I added the limit switches and now I’m ready to home the machine. I started on the settings of machine coordinates and enabled the limit switches. Then I ran, or at least I thought I did, ran the homing program. It did one of two things. It either hit the switch and sent an alert or when disabled limit switches it hit the end of the gantry and sounded like it was going to break. At that point I stopped the program and started over. So, my question is how I get to an initial start point to find home. Sort of frustrated at this point. I’ve read the set up on the assembly of the limit switches but It seems foreign to me. I’m trying to learn so any info would be helpful. Thank you.
You might give this thread a read. If it does not answer your issue, the topic requests that you post your message on it. Good luck and have a good evening.
Edit: I do have experience with my limit switches which I added to the Pro table back in November. One thing that really was important was to follow the warnings to update FireControl. Even if it is telling you to update to 1.5 even though you have 1.6, do it. Earlier this year that was an issue and I have not seen an explanation. What it did was updated to 1.5 and then when it restarted, nagged me to update to 1.6. I did both. You need to turn your machine off and then back on for everything to work right with the update when it is done.
Usually, people are reporting that the gantry is moving the wrong direction. That is when they are told to turn off the enclosure and start over and that seems to get everything in sync again.
If you are able to move X and Y with the typical FireControl keys, homing should go to the left back corner. If the limit switch failed to stop the movement, it is not working. While FireControl is active, just press one of the limit switches without asking it to home. That should throw an alarm. If it doesn’t, then you know the switch is not working (whether it is the switch, the wire or the connectors - you will need to sort thru that).
How did things work out?
Greetings. I just had time to work on this and I believe it’s working. I homed the machine to “machine home” and as I just touched the limited switches, I enabled the switches, zeroed and homed. The switches seem to be working great. Now, If I go to “work home” and home it, should the x and y automatically go to the opposite corner to start a work piece that I want to cut , or do I need to physically move the x and y to the opposite corner, set them as my work zero and this would be where I would start my work piece to cut?
That differs from user to user. Some of us are stuck in the previous world of orienting the drawing with the lower left corner: and continue to do that even with the limit switches.
What is important to do is to zero all axis of the workspace and the origin of your drawing at the same spot, irregardless of what the machine says is x=zero, y=zero.
Thank you. This makes it much easier. Appreciate the
help!
