Warm up code

[Mtw fdu]

I have watched a few videos on Youtube in regards to a warmup procedure that Langmire system has.

Can anyone post that code up to be used on other machines. Haven't seen anything else posted by other tables manufacturers.

I have done something myself but have not tested it yet. Just seeing if it might be the same or similar.

This is what I have done.

N01
N02
N03
N04
N05
N06
N07
N08 G21
N09 G53 G90 G40
N10 G00 X1200.000 Y1200.000
N11 G00 X0. Y0.

The numbers continues to go up and I repeat the N10 and N11 lines so many times. The numbers from N01 to N07 are just program name, dates,and controller information etc. Basically setting to go diagonal across and back again. This is only for both x and y axis. I haven't worried about do the intial touch off at the beginning of a normal run of a program.

Thanks in advance.

Interesting, I have not heard of this on a plasma table. I do warm up the spindle on my mill before machining. You do this to warm the motors up? Are they stepper or servo motors on your machine?

I haven't done it yet but have seen it on a YouTube video.

Here is the video. It begins at 11:30 part of the video.


I have never seen or heard of it either.

This is something that I have not heard of before for cnc plasma tables - and I'm not quite sure why it would be necessary - other than to simply home the machine. My Plasmacam table has something called "initialize" which moves the x,y, and z away from the home position by a small amount and then slowly moves back to the home position until the x and y limit switches are triggered. The z is a stepper motor and simply stalls as it hits the hard stop to zero it.

Both of my cnc wood routers (Avid CNC/Mach3 and Avid CNC /Centroid) also have homing routines that are run at the beginning of each session to home the machines to 0,0,0. For cnc mills and lathes, it is common to run "warm-up" routines to either home and/or warm up the spindle. I'm really not sure why the stepper motors on the Langmuir should need to be warmed up - other than to home the machine.

Thanks for the comments David.

I have never heard of it either before. But the video shows it not doing any "homing" as such either. I run cnc lathes and mills where I work and they warm up there spindle without question. Everything is done by the book.

This is why I brought this to the attention of everyone here. I hoped to have some one who own a langmiur table to chime in.

I had a Langmuir table, and that was the breaking procedure to test full movement of the table.
On my Dynatorch, i simply send the gantry to the far end of the table after initially turning it on to get grease moving in the linear bearings, especially in the winter months.

Well that makes sense. A breaking in procedure. Certainly explains alot.

Thanks for the reply Rockler.

[weldguy]

That does make more sense that this procedure is just to test for smooth motion, full axis travel, etc, thanks ROKCRLER.

I am ASSuming the OP is referring to the break in procedure...
here is the assembly page that mentions the break in procedure as well as the downloads page

Thanks everyone for your comments. Much appreciated.

For those of us who are very space limited, "warming up" or running a break in cycle before I cut anything helps me to make sure my rails and screws are clear and dont have anything that would cause a bind and ruin a cut. TABLE is in the name and some of us have to use it as such for grinding and cleanup lol

That's a very good perspective on the warm up cycle. Good thinking.
