General Mach Discussion / Re: Mach3 turn threading problem with Z feedrate

« on: February 13, 2020, 07:51:18 AM »

Christian,
- Are you using current reduction on the drives?
  1. I would suggest that you make sure that the current setting is correct for the steppers that you are using.
  2. Set drive SW4 to ON.
  3. Test axis  motion with steps per resolution seting of 2000 .(ie; need to set SW5,6,7,8)

Mach configuration:
  1. Tune the the steppers for velocity and acceleration and make sure the steps per unit are correct.
  2. Notice you are using Backlash for the Z axis. That SUCKS for threading! Test the axis motion with it
      off. ( .15 mm = .006" backlash )
      You have no backlash in the x axis?
  3. Can you set your set the spindle speed manualy?
      Mach3 and spindle control may be "fighting each other" for control of the feedrate during thread   
      cycle.

Christian,

Post your xml file  that you are using for the lathe. Just make a copy of the xml and rename it to something like
CHRIS RICH.XML and post it.

I see you are using  a modified screen set. Did you create or modifiy the standard 1024.lset?
Where did that screen set come from?

Run the "DriverTest.exe" file. How close is the Pulses per second in the test as compared to configured
Kernal Speed you selected in Port & Pins? (ie; test  shows 23506 as compared to 25000 HZ)
How clean is the graphics screen? Play with you mouse when you run the test, see what happens!..... that's why you should not play with the mouse when running  as you did in the video.

What version of Mach are you using?  Use Version R3.043.062

Use the Simple Threading (lathe) Wizard to generate the threading gcode. Fill in the required data, click Post Code, Click calc number of passes then you will see if you are exceeding  max feed rate.
( I would suggest that the code output be in G32 as it gives you info on each pass in case someting is wrong)

------------------------------------------------------------------
Some additional questions:

What are you using to acquire the index signal?

How steady is your RPM for whatever you set it at?
 Just for info you could check your rpm with a tack,but,let me say that Mach's rpm dro is more accurate than any tack you may have.

What drives are you using? If it's one of those chimes drive TB*********x ........ your on your owne as I can't help you!

more after you reply,

RICH

Christian,

I suggest you have a read of "Threading On The Lathe - Mach3 Turn".

Mach4 General Discussion / Re: Serious problems with G76 cycle in Mach4 Lathe and CSMIO IP S

« on: February 03, 2020, 09:54:36 AM »

You need to ask CS Labs how it's motion controller handles varying spindle speed at both index time and during the actual threading. Also find out how current their plugin is with the current version of Mach4.

The above is different than:
CSMIO-ENC from machine start, spindle activation, and Index signal finding it starts to count encoder position, spindle angle, and speed. All the information are transferred by the CAN bus to a CSMIO/IP motion controller, where they are treated by algorithms which task is to accurately and smoothly synchronize move of a Z-axis to a spindle during G32 or M84 command activation. At the moment of threading when the Z axis moves, the CSMIO/IP motion controller sends current axis position to Mach3, so its Z-axis position DRO shows the real position.

daniba,

I will post a few "simple" tests that you need to do. Leaving for a trip very shortly.
I'll post them when I get back in a few days.

Till then,

Where is the Machscreen 'manual'

There is some info / videos on Klaus's site.
I know of no specific manual, just have to play with the program to learn.

Beer1970,

Curious about the bullet turning wizard request.
Maybe start a new tread to explore the idea further.
or
Maybe discuss it further in the other thread you posted about a turning wizard?

Mach4 General Discussion / Re: Tool Change macro M56 and T0101 etc. problem

« on: January 11, 2020, 04:59:35 AM »

I don't use Mach4 Lathe or Mill but there are folks in here who do and hopefully someone  will reply.

I didn't see M6 listed in the manual which seemed rather odd. M??? are custom maco's that are user created. M6 is a industry standard for tool change.

See if  there is a configuration setting in Mach4 ( similar to Mach3) which provides option for use of a  tool  change?

Sorry can't be of any further help.......,

RICH
