（resolved）The "classicladder numPhysInputs" parameter does not take effect. was created by Soccer Kid

（resolved）The "classicladder numPhysInputs" parameter does not take effect.

Category: ClassicLadder

Hello everyone, when I was configuring the calssicladder, the number of corresponding physical inputs was always limited to no more than 16 points.

debug:
linuxcnc TPMOD=tpmod HOMEMOD=homemod EMCMOT=motmod
Note: Using POSIX realtime
Found file(REL): ./L510G_servo.hal
*** hal/components/xyzab_tdr_kins.comp setup ok
Found file(REL): ./calssicladder.hal
creating ladder-state
./calssicladder.hal:87: Pin 'lcec.1.input.in1-16' does not exist
Shutting down and cleaning up LinuxCNC...


Due to my negligence, the bed used an unknown PIN-16... This was not caused by a software issue.

Apparently lost after upgrading to 2.9.4, can you check again, please?

Wiring up for 7i92T reflash

Category: Driver Boards

I spent some more time on this tonight and after fixing some Python bugs and rechecking the wiring again, I hooked up my logic analyzer and verified that communication appears to be happening on the JTAG lines, I see mostly TDI with some responses on TDO, and clock signals appear to be working too.

I've done a quick drawing of how things are connected with the FT2232H Mini Module, as the pinout for the ports seems to differ from that of the FT4232H, and after checking the pins just to be safe, I see no data coming out of them, so I assume this setup is correct, matching port for port between the two modules.

I can run init95t and it seems like it attempts to program, and then cause a reset of the board, but the board goes right back into the same mode, with /DONE lit constantly, and no link lights on the ethernet:

./init95t  
Programming using Board Profile: Generic Board Profile Using FT2232H
jtag programming started!
JTAG Programming on ftdi://0x0403:0x6010:FT9MCMFR/2
Programming 'outflow/seveni95t.bit' via JTAG at freq 3.0 MHz
Device ID read from JTAG: 0x00210A79
... finished with JTAG programming
waiting for reset
Old Name:  
Connection timed out

I'm not sure why it's not liking the file being programmed but I also attempted with the ethernet jumpers in various positions, and had no luck with that either.
Not sure if there's anything obvious wrong with this setup... I've attached a schematic of the wiring and the saleae Logic file as well as a picture of the logic capture. 

I should specify that the pin numbers used in the drawing are the ones from the datasheet and the ones on the JTAG match up with what is listed in the manual for that board.

Mesa 7i97T & LinuxCNC setup struggles

Category: Installing LinuxCNC

im starting to think i might have something else going on.

with your point in the right direction and reading the documentation again, this time having had more exposure to terminology, i can find the modes and how to switch them. ive looked into the above three options and i think for now atleast i will run them as is, in torque mode.

Ive since double checked the servo drive settings and balanced it all so there is no movement when enabled. the drives also have a handy test option which internally feeds a +/-10v signal into the input for testing, this confirms the drive is set well and the motor functions very nicely. in fact the settings I landed on are near enough exactly the same as the remaining two untouched, as delivered, pulled from working machine (which much have been setup to run torque mode.

however when it comes time to have linuxcnc command movements, nothing is really behaving as i would expect, and i cant even begin to work through your above torque mode tuning process, because if i put even a 1 in the D field i get instant following error and a blip on the motor (P & I - 0), FF1 tried several 0 thru 1 ect), deadband 0.0001

ive confirmed its not runaway, because changing the sign on the scale makes that blip noticeable worse, presumably this is runway before the following error cuts it off.

the servo drive is now back in the same configuration it was when i began trying to incorrectly tune with tommys velocity mode guide so all info with reguard to some unstable movements with low P value, is still relevant, nothing useable though. Ive attached hal and ini files incase relevant.

given my struggles have quickly moved on from software installation into the seemingly typical noob hardware problems, if the mods would prefer to move this into a more appropriate channel that's fine by me. 

as always, thanks for everyones help, as a try DIYer, please know how much it hurts to ask for help and how needed that help is, if im asking

Category: EtherCAT

DUH...... I think i fixed it.

COORDINATES = X
changed to
COORDINATES = XY


KINEMATICS = trivkins coordinates=X
changed to
KINEMATICS = trivkins coordinates=XY

oops.

weird how it didnt error out.

Hey Guys. Im working on my A6 stepperonline servos on the bench currently. I got one axis going. Im trying to get a second axis involved. I got it working and linuxcnc launches without fault. I can jog both axis slowly before homing. I can home joint1 (Y) and still able to slowly jog. once I home X, I can jog it quickly, but cant jog Y at all. and if I fight the Y servo (its holding position), there doesn't appear to be any encoder feedback either once x is homed.

Hmm I am usually more of a bad influence than inspiring but I'll take it haha.

That sounds awesome, are you aiming at using this for faster inputs/outputs that aren't suitable for shift registers/modbus/I2C ?

So theoretically if someone had a 6 axis closed loop to the controller milling machine the second FPGA could be used for the encoder feedback and maybe some extra IO?

QTPlasmac pierce delay handling was created by kworm

QTPlasmac pierce delay handling

Category: Plasmac

Hi,

I just got QTPlasmac (2.10 using buildbot instructions) going and starting to make some test cuts.  My plasma cutter (Thermal Dynamics Cutmaster 60i) has a ~2 second delay for gas purge before the pilot starts.  That means I have to add whatever actual pierce delay I need to the two seconds making it, for example, something like 2.5 seconds. After the cut is made there is post flow for 20 seconds and if you start a cut while post flow is active there is no delay and the pilot lights immediately making the pierce delay too long.  When the post flow stops after 20 seconds then the 2 second delay is back.  I know I could have two different materials... one for first cut and one for additional cuts and have my Fusion 360 post processor change materials but that seems like a bit of a hack.  Is there a way I could handle this in hal/script/component?

MaHa, why you up so early? :)
4:40AM here, going to bed right now.
And whatever the reason you are up so early, i hope it's a good one.

How’s it going.  So I recently switched over to GMOCCAPY from the traditional Axis interface.  I have to say it looks much nicer and I like how tool touchoff and setting g54 home positions is much more intuitive.  In Axis I always made the mistake of not selecting the correct joint when doing touchoff and accidentally set my tool length offset as a X or Y offset shift then go crash the machine during a run.  Anyways besides all that, I’m now wanting to go to the next level and start customizing the GMOCCAPY interface.  I want to start out with something simple like a machine running timer alert.  This would be an alert that tells me to oil the ways after 10hrs of runtime.  This way the oiling is perfect and scheduled saving on way oil.  Stuffs not cheap lol What I’m trying to make happen is a function that’s tied to the run button that then activates a timer and stores the time running in a file on the hard drive.  When the total time running = 10hrs reset the time and display a message saying: “The machine has been running for 10hrs now.  It is time to Oil the ways.”  Where should I start on this?  I know there’s a hal.program-is-run and a time.N.start.  Then what do I do?  time.N.start <= hal.program-is-run?  Sorry I’ve never programed python much but have some C#, Java, VB, SQL, C++,and XLM skills.  My collage sucked and never let us program in Python.

Or using "voltage dividers" made from 2 resistors for each input also works fine, but care must be taken to prevent the lower side resistor from disconnecting.
It does induce more current draw from outputs though, but i know for sure in most cases all is OK.

Oh yes, i did disagree with that statement, silently, as he might have experience with "Home" or "Office" types of HP computers and those are frankly cr@p, but "Enterprise" HP computers and workstations are magnificent in every way and some have 700W or 1000W power supplies despite no way of cramming stuff in it to require that kind of power. Same goes for Dell and Lenovo and Fujitsu and older Fujitsu-Siemens, all of those in the "Enterprise" edition work perfectly, no matter how old, and using them 24/7 is a given.
And yes, there are many of us here using HP even on industrial machines, as again, they never fail.
