VB and the development of wizards / Re: Use SystemWaitFor / IsActive ? And what about negative ToolLengthOffset ?

« on: August 07, 2015, 02:55:27 AM »

Thank you for your quick reply.

And sorry for my poor explanation previous:

I want to move to a position, stop movement, and THEN check via input if we are in position ?
It's for an ATC, that, picks up the tool holder, moves to a inductive sensor, stop, check that there is in fact a tool in the spindle before continuing.

Any comment in the negative tool length offset ?

Best Regards, Bo.

VB and the development of wizards / Use SystemWaitFor / IsActive ? And what about negative ToolLengthOffset ?

« on: August 07, 2015, 02:05:23 AM »

Dear All.

I'm fairly new to this VB, but getting the hang of it.

1)
Now I need to do an axis move until an (oem)input becomes active
On the net I found 2 commands "SystemWaitFor()" and "IsActive()" now which one to use correctly ?

Was thinking of making a While-loop with the "IsActive" ?

2) In the documentation I found that the ToolLength "SetToolParam(toolnum,2,yy) where yy must be a positive value ?
Is this true ? or can I use negative values also ?

Best Regards, Bo Andersen.

Tangent Corner / ?: Differential line driver IC's

« on: December 27, 2014, 01:38:42 AM »

Dear Forum.

I want to make a DIY PCB converting the 5V single ended outputs / 24V proximity switches. Into 24v differential signals, and back again.

So I'm looking for an IC that has 5-24 input capability, and 24V diff. output.

Anybody bee doing something similar ?

Best Regards, Bo Andersen.

SmoothStepper USB / ESS, can't reset limit switch with OEM trigger code 1021 ?

« on: December 23, 2014, 12:51:10 AM »

Dear Forum.

I'm quite new to ESS coming from Par Port.
So the ESS is hooket up, and running, simply replaced the cables to the 2 BOB's and, set the frequency and re-tuned the motors. That's it !

I also have an PoKeys 56U (USB connection) connected to a DIY operating panel.
Here I have a Push button  "Reset" that via the Pokeys give the OEM code 1021 which is "Reset"
This has been working fine with the Par-Port setup.

Changing to ESS. It seems that a "Limit flag" is set in the ESS, constantly triggering the E-stop of the system. (I can hear the computer speaker, constant beep every 4.th second) that it E-stops.
I cannot use the OEM code to Clear that limit flag, only the mouse click on the "Reset" on the screen, clears that flag.
Then my push button works, via the OEM code 1021.

Is this a bug or feature in ESS, that after a limit switch is hit, then a "double-click" on Reset is needed ?
Is there another way ?

Best Regards, Bo Andersen.

PoKeys / Re: Negative value in feed override using an encoder

« on: November 25, 2014, 01:28:05 PM »

+1 as I have same problem.

Did you notice that the FOVR above 300% dosen't change the actual feed ? (So above 300% nothing happens, just like below 0%)

Building or Buying a Wood routing table.. Beginnners guide.. / Re: Working router table, options to increase travel speed ?

« on: November 03, 2014, 10:34:07 AM »

Hi All.
Thanks for your feedback.

Not blaming anybody/anything other than my ignorance in all the diy stuff that I do.
I just figured that a 5mm pitch would work, and i does. But now it seems 10-40 mm would be even better :-)

The voltage is 48V, and my drivers can go up to 60V. I can try to crank up the voltage, but it's only fine tuning so i guess it can only be 50-52V perhaps.

Best regards, Bo Andersen.

Building or Buying a Wood routing table.. Beginnners guide.. / Working router table, options to increase travel speed ?

« on: November 02, 2014, 01:22:59 AM »

Dear All.
I guess you could call this a luxury problem.

I have a functioning router table, of a gantry type. It's all driven by 3-phase steppers 3.1Nm
The gantry (Y-axis) is driven by 2 motors one for each "leg" and the linkage is 5mm pitch ballscrews.

So, the Y travel speed max. out at approx 4500-5000 mm/min (~180~200 IPM) where one of the steppers loose the steps and comes to a halt.
Currently i run it at max. 4000 (~160 IPM) to be on the safe side.

I guess that around the motor speed of 1000 RPM (5000 mm/min / 5mm pitch = 1000 RPM) the stepper greatly is reduced in torque.

Options to increase speed:
1) Looking into AC Servos. I'm a bit scared of them, never used, setup, tuned or what so ever with a motor and drive. Still I think this could be fun.
Any recomendation for an "easy to install" kind of thing. Is there any preferred brand to look for, do I need software or can I get a turnkey preset system  

2) Change ballscrews, this would be rather "cheap", as I can get a 10mm pitch ballscrew, that fits directly into my current setup. No modification at all to the table, or electronics.  

3) Hybrid steppers, a stepmotor with a feedback encoder. But how can that be faster if it simply max. out and looses steps like the regular stepper  

4) Shut up,be Happy, go to the garage, grab a beer, get those chips flying  

Best Regards, Bo Andersen

PoKeys / PoExtBusOC, invert output ?

« on: October 26, 2014, 12:38:03 AM »

Dear PoLabs.

I really miss to able Invert the outputs for the Output-extention boards.
This can be done on the main board it self, but not on the extension.

Please please please, put this bit_toggle on the todo list for monday

Show"N"Tell ( What you have made with your CNC machine.) / Re: An operating panel for MACH3

« on: February 09, 2014, 12:41:37 PM »

I tried Pokeys for jogging and found it had too much of a lag.  Have you done anything special for jogging?
Vince

I have not been tweeking anywhere, however I found there is 2 ways of mapping the push buttons.
One using the MACH3 OEM-codes that "hooks" directly in to MACH3, and some IO-stuff that I think "simulates" button pres somehow !?
In this video you can see/hear the difference. And I show how I set mine up.
Pls. ask again if anything is unclear.
