Need help setting up XYYZA for stepper motors

Category: General LinuxCNC Questions

That's an odd error as a parallel port in mode "out" should have pin 16

Can you comment out any line that causes an error, launch LinuxCNC
and then in a terminal type:

halcmd show pin parport

and show the results here

Gmoccapy - spindle restarts at program stop

Category: Gmoccapy

Looks like this might be limited to spindle speed and direction pins not consistently reacting to a program stop as 'spindle.0.on' seems to always clear.


 


Good catch. I will look at these pins in case it happens again. I had it only a few times when milling PCBs. Other than that it never occurred...

Hi

I am currently setting up my 3D Probe. I declared the probe as T99 in the table. In addition to that, I set Variable 4012 in my *.var to 99.
4000    0.000000
4001    1.000000
4002    2.000000
4003    3.000000
4004    4.000000
4005    5.000000
4006    6.000000
4007    7.000000
4008    8.000000
4009    9.000000
4010    10.000000
4011    11.000000
4012    99.000000
4013    0.000000
4014    0.000000
However, when I command the Tool to be picked from the Toolrack, I  get the message "T99 not found in carousel". All the others (I actually tested only Tool 1-7) are working. Is there something I am missing?

One additional question. After inserting the Tool manually, I am using the Angle function. It works so far and I get an angle reported. However, I assume that, when clicking "Set rotation WCO", that the rotation is saved in my WCO. However, looking at the Offsets Screen, it looks like it's still 0 (I assume that would be R?).  Is this correct?

bandit controller retrofit

Category: General LinuxCNC Questions

Here's a thread of someone else doing a similar retrofit:

www.cnczone.com/forums/uncategorised-met...253-engineering.html

The existing drives are 2 phase, unipolar, and 8A 
(Unipolar is why they have 6 motor wires because each winding has a center tap)

I think the forum suggestion is good: Replace the drives with standard bipolar
stepper drives but since the windings  are wired in series for a bipolar connection,
use the highest voltage capable drive you can get.

(this assumes you want to keep the motors)

I would probably choose a 7I96S setup as it's closer hardware wise to the 7C80.
Then the main changes would be to change the driver name and card name
and all "inm" to "inmux"

Unfortunately the locale bug is a known pncconf issue and the only known work-around
is to set the locale to  english.

If you launch pncconf from a terminal, it may be sufficient to type 

LANG=C

before launching pncconf

tangential knife along multiple layer height

Category: AXIS

Hi Vre,

This for info. I hope you can use it.

The linuxcnc scurve planner has now tangential knife output value to hal.
The hal rotational output value could be coupled to a axis motor or device for rotation.

Within the the planner you can also benefit from the clothoid fillets, where the path
tends to be g3 continu, ideal for a drag knife application.

You need to use menuconfig to setup your locale.
If you go to this thread it is an index to a lot of info.

Pokeys_homecomp EncoderSearch / Encoder Arm Topic: Pos_Fb Following errors

Category: HAL

i now tried to extend the homing workflow to better align to the Linuxcnc usual homing.

my home states are :

PK_PEAxisState_axREADY   -> before homing
when Homing is triggered the pokeys internal Homingprocedure does the following states
 - PK_PEAxisState_axHOMINGSTART 
 - PK_PEAxisState_axHOMINGSEARCH 
 - PK_PEAxisState_axHOMINGBACK 
- PK_PEAxisState_axHOMING_RESETTING
- PK_PEAxisState_axHOMING_BACKING_OFF
 - (  PK_PEAxisState_axHOME ) that status of pulse engine is suppresed and 

after that i have to finalize the pokeys homing procedure by a "PK_PEv2_HomingFinish" command in order to operate that joint again for tho upcoming steps there fore i added two additional steps: 
    PEAxisState_axReadyToFinalizeHoming  -  used as a indicator from pokeys.comp to pokeys_homecomp that the homing finalize command can be triggered

    PK_PEAxisState_axReadyToArmEncoder  in this step that index search part should take place, in that step my intention was to reset the position feedback to ZERO_POSITION, to prevent problems on pokeys due to the (softlimits on the device side).

on the Joint for Z i have the problem that the difference to zero position is quite high as the position change might be 100 mm

so here i'm at a point  where i don't figure out what to do, and either where to find out or whom to ask for help.

what i currently try to do is 
Joint_num].index_enable = index_search_active;  at the PK_PEAxisState_axReadyToArmEncoder status


and at the follwoing status
PK_PEAxisState_axHOMINGARMENCODER  i basically reuse the actions as were done in homing.c at "HOME_INDEX_SEARCH_WAIT"

                if (H[joint_num].index_enable == index_search_armed) {
                    /* yes, stop motion */
                    joint->free_tp.enable = 0;

                    // joint->free_tp.pos_cmd = joint->free_tp.curr_pos; // set to zero
                    joint->free_tp.pos_cmd = 0; // set to zero

                    /* Pokeys resets encoder position to zeros */
                    H[joint_num].index_enable = index_search_armed;

                    H[joint_num].homing = 1;
                    H[joint_num].home_state = HOME_SET_INDEX_POSITION;
                }


but it always stops at about that step and some part triggers "do_cancel_homing"
the only message that i could see on my last version was 
"emc/task/taskintf.cc 976: Error on joint 3, command number 139"

(until now a similar message was together with a FOLLOWING_ERROR for that joint)

Is there someone who could tell me where to check, or whom to ask. I'm not sure if this thread is the right place to ask about that topic.

Is there a good source on how to set this card up?

PnCconfig doesn't have the 7C80 and i am not very good with the HAL files yet.
I tried to use PnCconfig and chose the 7I76 instead, but then at the end PnC got an error saying "unsupported locale setting".
