TM-1 & Hold to run switch

[truline]

We just purchased a TM-1. The damn thing has a hold to run switch on it which totally negates the purpose that we purchased the machine for. What good is it if you can't execute automated machining and wak away from it for till the end of its cycle and come back. We're a small company and we cannot afford a bigger machining center so.

Does anyone have any solutions or codes to disable the hold to run switch?

Lost in CNC Hell.

A picture is worth a thousand words.

Have you ever had the clip fall off during operation?

No.

I took the picture with the clip hanging from the little bracket on the machine. Normally the switch sits in the bracket so there is no weight on the clip. This is actually on a TL1 but the TM is the same I think.

To my knowledge there is no way to disable this switch in the software. It is a liability issue with the open machines. If you want to run the machine unattended I recommend you remove the handwheels and make covers for the exposed shaft end. I think they pose a risk just as serious as the spinning tool as they could snag clothing and not be noticed until someone was well wrapped up.

Yes, it looks like the same switch and I understand about the liability issue. I have had smaller open milling machines running in my shop for the past ten years and I am now needing to step up to a larger machhine to meet the business demand.

The hand wheels are smooth and do not have any cranks on them so I do not anticipate any issues there. The shaft ends are covered already.

My question was posted as I will be machining parts with taps, drills and end mills most of the tools are 1/4" or smaller so I am concerned about the switch falling out of the clip and the machine breaking tools which I think is more likely what will happen if the switch is dropped.

Yes, I think it is more likely a human operator would fall asleep from boredom and drop the switch . A metal clip has a very high boredom threshold.

Just shut off setting 51. At least this works on my 2003 TM-1.

To do it quick
Hit the SETNG/GRAPH Button to go into settings page.
Type 51 then hit the down arrow cursur key this take you to the setting 51.
Hit right arrow to turn setting off.
hit enter key.

You will have to do this every time you power up.

Not responsible for harm which may come to you or your machine caused by the disabling the hold to run switch.

You can also change Parameter 57 bit 32? Door Stop Spindle to a 0.

If you don't know how to do that. I'll walk you thru it.

E-stop machine.
turn setting 7 off.
Press Para/Diag key once.
Press Home (should take you to par 57 if your not there already)
Door Stop Spindle should be the last parameter on the right colum.
highlight it and press 0 then write/enter.

This should work. But keep in mind that it was set for a reason, although rarely practical it serves a purpose.

Does this change stay resident after powerdown unlike to setting 51?

Thank you everyone for your input the Haas installer is here today and the first thing he did was to go into the settings and use code 51 to disable the switch. So it is all good for us here.

Yes it stays were you put it, it doesn't reset after restart. You still will have to turn setting 51 off. But you should be able to run the spindle with the "door opened". Its a standard parameter on all mills, i usually always turn it off on installs, per customer request.

OK I misunderstood. I thought you where saying how to bypass needing to change setting 51. I figure there is a way since our 01 tm-1 has no saftey switch, only a plastic blank off plate, and does not require it as the 02 does and the setting is disabled at power on.
