HAAS TL-1 post processor

[Anonymous]

So I have a HAAS TL-1 that I'm trying to run some parts on using fusion 360 CAM. I'm using the most recent generic HAAS post processor but I keep getting errors like x over travel and z over travel. I've tried messing with my offset in both fusion and on the machine and keep getting the same thing. Can someone point me in the right direction as far as a how to video or a better post processor that works for the TL lathes. I'm starting to think that the generic post for HAAS turning is for there slant bed lathes. Thanks in advance.

Can you share a sample part and posted code with notes about where the machine alarms out? This could be a post issue but we are using a TL-3 with the generic Haas turning post (until I get around to modifying it to suit) and have no issues with this, although we are removing all G53 moves by hand currently (we have almost never programmed this machine with CAM until recently).

I am have the same issues did you locate a fix for this?

Same issue here.  Generic Haas Turning post on a TL-1.

A super easy facing operation.  It says Z exceeds limits when there is no way it should.

G54 is the front edge of the part, and tool 1 offset is the front edge of the part.  Verified.

@brettrayrichardson 
Sorry I didn't get back to you months ago, I haven't been at that job for over two years now and I don't remember what we did to fix the issue. Hopefully you've found a solution by now.

@rw_skinner 

Your issue almost seems as though G54 isn't set up and the machine is trying to travel past G53Z0 which (if I remember correctly on our TL3) was all the way at the tail end of the machine at the limit switch.

First Haas so its taking a little getting used to.

MDI works fine.  If I do this below the tip of tool 1 is exactly where it should be.  1.00" OD stock, it will be on the face and outside edge of the part by the 0.010" I ask for.  No Errors

G54 T1;

G0 x1.010 z0.010

I set up a single tool for starters.

Tool Offsets, Tool 1

Faced part, Set Z Face

Turned the diameter,  Set X Diameter and entered measured value.

No, to Work offsets,  G54

Go to face of the part and enter the machine Z position  -23.7455

Go to OD of part and touch, Add the machine offset for X and the part measurement   -10.535 + -1.00" OD = -11.535

G54 T1

G0 X0. Z0.

Will take me to the center of the part on it's face as desired.

Seems like I'm doing my offsets correct.

BUT any IPS stuff or post from 360 will give me the errors.

[Steinwerks]

Unfortunately I can't see anything offhand in the code that would result in that error and no longer have a Haas to test with so I'm a bit stumped. Perhaps someone else will chime in with some insights.

[rw_skinner]

It has nothing to do with the Fusion Post.  It has everything to do with the TL Operations Manual telling users how to incorrectly enter offsets.  It basically has then entering in the same machine coordinates for G54 as tool 1, instead of the "difference if any"   If tool 1 is touched off the part's OD and face, then G54 will basically be 0,0 because there is no difference.

If you measure all your tool lengths from the spindle, then G54 should be the distance from the spindle to the face of the part.  X should be zero because we're using the x offset of the tool.

At least, when I did it this way it seems to work.

Hi, i have this same problem on My first CNC lathe.

Program is stopped in Z over travel range
Anyone can help me?

What is your G54 offset for Z set to?

[Anonymous]

In your G-code sample, tool is not picking up offset, at first G0 block machine alarms because it has no reference to tool position in work envelope.

You have to measure tool offset and register values in Geometry offset, set G54 origin in same place on machine and in Fusion, model face and centerline.
