[Emc-users] Spurious edge on startup

I have a HAL which is detecting a false edge when loading LinuxCNC. I have AM882 drives which have an Alarm signal output, and an Enable signal input. Alarm is active-low, Enable is active by default unless LinuxCNC deasserts it, all goes through a 7i92 card. The Alarm signal is tied to its

Re: [Emc-users] Can't figure out homing on gantry

iggered them. They respond. At one point I switched the connection for gantry.0.joint.00.home and gantry.0.joint.01.home, just in case I was using the switch for X1 on what was actually the drive for X2. It was a good theory, but it didn't change anything. Danny > > > > On 9/5/20

Re: [Emc-users] How do stepper drivers work?

From the user side, you provide 5v step/dir signals and need to pay attention to which active edge the driver uses, and know the microstep multiplier inside the drive. Inside, it's a constant-current PWM. If it's microstepping, it advances through a sinusoidal approximation of current

Re: [Emc-users] Using 7i76 I/O as serial Rx/Tx?

I'd asked them about using a 7i92 to drive an RS485 transceiver, which would require 4 signals. They said the functionality was planned but no specific date. I asked if it would just appear as a Com port, he said no it'd be a specific LinuxCNC driver. There's a "UART" listed on the 7i92's

[Emc-users] G0 vs G1-specific functions?

Two-parter here: I was looking over another carving job on the preview window and realized there's really no way to tell where the work is. That is, we go up to Z=2" for the start/end coords, but I need to know where the carving itself starts. It's shown in a different color because it's all

[Emc-users] Major lags when zeroing axes

I work a lot with 3D carving. The files are often quite huge. When I go to zero the work coordinates, EACH axis results in recalculating the entire file, which can take minutes. Really it shouldn't require any recalculation (Mach3 doesn't) since it's just offsetting the coordinates, but I

[Emc-users] Moving axis while paused

Recently discovered this: When paused, the axes can't be moved by the user. While that sounds like a safe protection at first, that's actually a critical problem. It is not uncommon to have to "fix" something mid-run. In a few cases I've seen the CNC router pop freed pieces out and they

[Emc-users] Spindle control panel breaks LinuxCNC?

I have an X200 VFD. M3,M5,S18000 work fine, from MDI or code. My MPG's "spindle" button works. On the default panel, there's a "Spindle" button flanked with a CW/CCW indicator. Clicking any of that doesn't make the spindle go, even with "S" set to a valid RPM. It's not JUST that. Once you

Max vel 15, max accel 50. That cuts like 1" radius arcs. But the docs are saying that's basically what G64 with no P-parameter does, basically totally disregarding accuracy to keep the feedrate up. Danny On 6/4/2016 4:16 PM, andy pugh wrote: > On 4 June 2016 at 20:20, Danny Mil

[Emc-users] Vectric Aspire 8.0 generates bad code for LinuxCNC

I've seen this several times... So Vectric Aspire 8.0 is a great program. Most of the time it works ok. However, we've found Gcode generation sometimes yield just this: G64 No "P0.001" parameter. Well that's pretty damn toxic, it'll create huge arcs instead of what it's supposed to do.

Re: [Emc-users] Linuxcnc and Arduino

I'm not sure what context you're saying you have for the XHC. I have he XHC-HB04 on LinuxCNC RT on the Linux RT kernel. It's a VERY smooth response, but partly because my machine is very fast. There is, however, a case for time delay if you select jogmode=normal and not =vnormal on a slower

[Emc-users] Copying an installation

So as per previous thread, I may be moving this to another PC. And probably change to an SSHD. I spent a ridiculous amount of time getting the OS and LinuxCNC RT installed and configured. And I didn't do all of it myself so it's not a straight shot to repeat. I'm just saying if I start from
