Advanced Search

Well, I will need to orientate it for the changer. I was thinking that I can just run it velocity mode and use the encoder to orientate it. I did see something about a homing feature. However I will need to double check that.

HOME_SEARCH_VEL = -0.083333

That's 0.083 inches per second or ~ 5 Inches Per Minute (IPM)
= Really slow

the MAX_ACCELERATION and MAX_VELOCITY is different on my machine right now. (this is before experimenting)

What you are seeing is probably a limit to the speed with which steps can be generated. Once the system hits the maximum step-rate the system will realise that the machine is out of position and trigger a following-error.

What is your step length and step space? Add them together, and divide into one second. That's the maximum number of steps per second that the system can generate. You are probably hitting either this limit, or the limit of the base-thread speed, as the system can generate at most one step per base period. (If you don't see a "reset" function in your HAL then it is one step every two base thread cycles.

If the driver can handle it you can try reducing step length, or the base thread period. But you might find that the only answer is to change the microstep ratio.

Your lathe could be configured as xzuw, which would probably make sense, though I don't think that canned cycles are supported in the uw plane, nor is radius/diameter mode, as far as I can recall.

Note that the mapping between the "joints" and the "axes" is governed by the kinematics module and and configuration. It may be that something is a bit wrong there in your configuration.

If you attach your HAL and INI file we will have more to go on.

Does adding the option here work?

Hallo spicer,

hab in der axis_mm.ini bei Achse_0 und Achse_1 auf 0 umgestellt. Bei Achse_2 war default eine 0 schon drinnen.
Ich kann obwohl die Fehlermeldung noch ersheint eine Referenzfahrt durchführen. Das einzige was mir nun aufgefallen ist, das wenn ich mein Programm ablaufen lasse und es irgendwo stoppe wird bei einer erneuten  Referenzfahrt dieser Startpunkt als Referenzfahrt genommen wird. Sollte eigentlich so wie in der axis.ngc in der unteren Ecke liegen. Wo finde ich eigendlich das Startprogramm axis.ngc?

MfG.

 

Dear Andy,
Thank you for your reply.

I would like to install central lubrication on the machine.
FUW400-5A-75E.gpio.25.in-not: this bit is connection oil pressure switch.
FUW400-5A-75E.gpio.26.in-not: this bit is connection oil level switch.

I would like to solve this:
If there is not enough oil level, then there should be no lubrication and write it on the screen.
If there is enough oil level, then lubrication can be set periodically, for a given time.
If lubrication has started, then watch whether the pressure switch switches during a given time. If it does not switch, then write it on the screen.

I don't have any relevant experience but... Does the current driver offer spindle orientation for tool changes, and do you need that?
If so, does the now motor support that (I would be surprised if it doesn't, it seems to be a servo drive)
