Correct me if I am wrong, being all new to this, but that first bit of "code" you listed there looks to be from a .hal file and not an .ini file? If so then that gets me even further along and might be enough for me to get dangerous and take a stab at it.

What do you mean with "SoE"?
Maybe i try to get a used Beckhoff AX5xx from eBay when thats easyer to use with LCNC.

... the SIEMENS etherCAT pcb is hard to get. it starts to annoying me...


endian post=327010 userid=29161
AX5xxx from beckhoff is SoE and it can be pain to create custom .xml which should be editable out of Sachas own .xml files...
 


SoE does mean - Sercos over Ethercat ... similar to CoE - CANopen over Ethercat ... You can imagine that ethercat itself is a empty lorry train were many different buses/networks shape members can sit a transport itself where they are need ..but very fast, synchro and with many many diagnostic stuff

I have never creating custom .xml file for them only for CoE stuff I have done it... I think if you are basic user it should be enough for you to use .xml config from saschas shop but ... it has many many very usefull stuff as monitoring the native I/Os ... external encoder - basically for external encoder as linear scales to run velocity loop over them ...

hmm i thought we had a full config somewhere with spindle. I guess its time to make one (aka copy flexihal). Ill try to mash out a regular config based on my setup

yes the config wizards will be less than helpful in most cases. limits are easy, but estop is a case by case basis depending on how you wish to wire/config your estop. tux posted his estop example a few pages back, and there is an estop example in the remora docs hal section.

for the ini file, yes read the manual, but dont start adding a bunch of options that might not apply to remora.

based on my friends rast's config, the endstops might look like this depending if you do a limit or a limit+ home config. it looks like he has included both in his ini file.
# end-stops
#pin IN03
	#net X-max       remora.input.06        =>  joint.0.pos-lim-sw-in
	net both-x       remora.input.06        =>  joint.0.home-sw-in joint.0.pos-lim-sw-in
#pin IN04
	#net X-min       remora.input.07         =>  joint.0.neg-lim-sw-in
#pin IN05
	#net Y-max       remora.input.08         =>  joint.1.pos-lim-sw-in
	net both-y       remora.input.08        =>  joint.1.home-sw-in joint.1.pos-lim-sw-in
#pin IN06	
	#net Y-min       remora.input.09         =>  joint.1.neg-lim-sw-in
#pin IN07
	net both-z       remora.input.10         =>  joint.2.pos-lim-sw-in


the important part is making sure your remora.input.xx match the config.txt file. from the nvem config, label IN03 on the cover of the NVEM board is connected top data bit 6, aka remora.input.06

	"Thread": "Servo",

Beginner Building a CNC - Questions About EtherCAT with Delta A2 and In

Category: General LinuxCNC Questions

Some ethercat drives offer built in digital IO that can be used. Ideally the VFD used would also have an ethercat interface.
Many VFDs also offer an RS485 (Modbus) interface which can also be connected to linuxcnc via a USB-RS485 adapter.

LPT can certainly work but it can be a bit tricky to find a PC with low enough latency.

Given the isolation of your market you might want to start out by looking for a used PC with an LPT and an ethernet port and see how low you can get the latency. Mind you, I have no idea how easy/cheap it is for you to find used PCs to try but this would give you an idea of what step rates you could get out of an LPT port solution before buying the drives.

[edit]
I think it should be possible to use ethercat for the drives and the LPT port with one of those cheap breakout boards for the digital IO and the VFD.

Thanks for that fast reply! OK, so if I am understanding correctly, the EC500.hal is universal for all 3 RT1052 based controllers and I just need to edit the .ini file for my machine?

I have uploaded the nvem-rt1052.txt to the controller, and that seems to of worked well.

Looking at the ini file I am now seeing what my first problem has been, as nothing is there but the config for X Y and Z. No Estop, limit switches, spindle, etc.. So at this point I will need to go and RTFM, (this? linuxcnc.org/docs/2.8/html/config/ini-config.html), on the ini file and try to figure out what I am suppose to put there to get the rest to go.

Given that I am unfortunately a 101% tactile learner, where would be the best place on the forum to ask my questions about what I'm getting wrong as I proceed with this editing attempt?

Thanks again for the info as I have not seen that part explained before. This is a bit of help in the right direction. I'll take it none of the configuration wizards will be of any help in this endeavor?

Do not wire Enable until you get things working.

 

Yep, on simple step drives, its a DISABLE input.

Brushless motors should last almost forever.

You can probably keep the old motors.

Motor drivers have improved a lot.

Motors are mostly the same today as they were 30 years ago.

The induction motor is a very, very old invention.

An old PC might actually be better than a Pi for latency.

Add RAM for sure.

The problem with a Pi is it has no power supply of its own.

I run the cooling fans of my 3 stepper drivers off the 12V rail of the PC controlling them (I made a cable to siphon off the PC's power).

Make sure to set the governor to performance; it helps latency a bit.

Run this in a terminal:
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor > /dev/null

I can be found everywhere, if you know where to look, but i do not think you need that, yet, this should be fairly easy to figure out.

darkpheonix try with this and go from there. if you are trying to set up a rotational axis, that is different than a linear axis in setup
[AXIS_Y]
MAX_VELOCITY = 5

these options are not real, and im unsure where you got them from.
