Re: N/O proximity sensor

Technically, N/C sensors provide better indications if a wire breaks etc.
A better way to think about it is this:

If triggering the sensor is supposed to cause machine motions to stop (e.g. a limit switch, emergency stop button, cycle-cancel button, etc.) then you should use an N.C. switch or ...

Re: M400 control not powering up

If it does not turn on at all when you apply AC power, then the next step is to momentarily short the motherboard's power-button pins together.

If the power supply does not turn on at all when you apply AC power and momentarily short the power-button pins together, then the power supply is probably ...

Re: Build Thread- Tree Journeyman 425 to Allin1dc

On an Allin1DC (and most any other DC-servo Centroid controller of the past 30 years), if you need to toggle Direction Reversal in order to make an axis move in the correct direction, then you also need to swap your inputs for the plus and minus limits on that axis.

Perhaps the installation manual ...

Re: Acorn custom plc not over written buy wizard

Of course, if your objective is to add CycleStart2 and FeedHold2 input assignments, and then have them work, you have to let the Wizard change your PLC program.

I was working with Janl last month on this last month.

The problems he had with the Wizard were not due to overwriting the PLC program ...

Re: Build Thread- Tree Journeyman 425 to Allin1dc

If all else fails, post a Report, plus a picture of the Alt-i display while you have just one axis on its non-home limit, and are unable to jog off.

Re: Build Thread- Tree Journeyman 425 to Allin1dc

Assuming you have six independent limit switches, wired to INP1 - INP6, and the directions are right and the software configuration is right, then yes: you should be able to jog minus to get off the plus limit, and you should be able to jog plus to get off the minus limit.

You need to be in Slow ...

Re: Build Thread for Bridgeport Torq-Cut 30

In your layout, don't forget to include distribution terminal blocks for your 24VDC for inputs; 24VDC for outputs; and 240VAC for the ATC motors and arm motor brake.

It will help if those terminals are close to where all of the I/O wires enter the cabinet via the gland panel below the main fuses ...

Re: Tool Offsets are not proper

I then use the functions to set Z zero to be the surface of a block of aluminum in the vise.
When you did that, what number was in the "Tool Number" field on the Part Setup screen?

If it was not already 10, you would need to arrow over there and enter "10" for the tool number, before you press F4 ...

Re: M400 control not powering up

There have been quite a few generations of M400 controls.

If yours was built between ca. 2003 and ca. 2015, so that it uses a micro-ATX motherboard and corresponding power supply, then the issue might just be that the motherboard battery is dead. See https://www.centroidcnc.com/dealersupport/tech ...

Re: Umbrella ATC - Acorn Compatible

When your TTS tool holders are inserted into the spindle, what would be the consequences of having metal chips stuck to them?

Does your ATC design incorporate an air blow through the spindle during tool changes?

With tapered tool holders, chips on the tapers will tend to stay there as the tool ...
