Tormach 1100MX???

Time goes by and. . . There is a Tormach 1100M setting in my shop ready to be converted into a 5 axis machine.

I am trying to figure out how to work with the Tormach EMC1 board and LinuxCNC. This board does not want to play well with LinuxCNC out of the box.

It does use hostmot2 and hm2_eth to connect. However they are special versions of the files to make it work correctly. In the tormach files there are versions of both of these files that are much larger than the ones installed by linuxcnc.

If I use the vanilla linuxcnc versions of the files then I get the following when I try to run a config that connects to the Tormach ECM1 board.
Code:

I have connected my install to a 7i76e and it connects and runs linuxcnc just fine.

I have copied the tormach hostmot2 and hm2_eth files to the /usr/lib/linuxcnc/modules folder and tried to run using their updated versions of the drivers. I get the following result.

What are your thoughts? I will need 5 axis of coordinated motion I can't get that from the ECM1 board anyway. Should I scrap that board and rewire to the 7i76e? I will ultimately want 9 total stepgens four of which don't need to be coordinated motion but they will be used for functions on the machine (toolchanger, W axis adjustment).

If I don't scrap the ECM1 board, can I run both the ECM1 and the 7i76e off a dedicated gigabit switch with one connection back to the main control computer or do I need to add another NIC to the control computer? I found the following link as a reference about using a gigabit switch. hm2-eth-multiple

If I scrap the ECM1 board, what is the best way to get more than 5 axis of step direction commands. Can I put a 7i76 on one of the expansion headers of the 7i76e and get more stepgens? Do I need to run two 7i76e cards?

What do you think?

hm2_eth: ERROR: Failed to execute '/sbin/sysctl -q net.ipv6.conf.eth0.disable_ipv6=1'

Seems like a path or missing executable issue

You can run up to 4 hm2 Ethernet cards using a switch but the read functions in the
hal file need to be changed to use read-request so that you can overlap the read operations
on the multiple cards. The cards also need to have different IP addresses, say 10.10.10.10, 10.10.10.11 etc

You can add 5 more stepgens to a 7I76e with a 7I76 but if you don't need the extra field I/O a
7I85S (4 more stepgens) or 7I88 (8 more stepgens) would do.

Good catch Peter. I did not notice where it was looking for /sbin/sysctl. I don't know how many times i had looked at the error logs.

However the file and path both exist. When I run /sbin/sysctl -a the variable "net.ipv6.conf.eth0.disable_ipv6" does not exist. In fact no "net.ipv6" variables exist. I believe this is turned off in the grub configuration kernel parameters.
Code:
quiet splash intel_idle.max_cstate=1 ipv6.disable=1 cgroup_enable=memory,cpu,cpuset swapaccount=1 usbcore.autosuspend=-1

I see that the missing directory is /proc/sys/net/ipv6

What is interesting is that this is the same for when I boot to the pathpilot partition and pathpilot works just fine.

To clear up how I am at the point I am at. I took an image of the existing pathpilot installation partition and replicated it to a new partition, lets call it the linuxcnc partition. I then installed linuxcnc 2.8.1 on the linuxcnc partition. I made a new configuration using information from the pathpilot .ini and .hal files to make a config that uses the linuxcnc 2.8 stuff and the pathpilot stuff.

I compiled the kernel 4.19.1-rt3 per Big John T's instructions for linux mint. That is what was installed on the pathpilot install from the factory.

Both of the kernels. 4.11.9-rt7 and 4.19.1-rt3 have terrible latency. Spikes between 100us and 200us are not uncommon. I have seen up to 215us.

I have not tried isolcpus yet. Do I put the isolcpus param in the grub line like the following? I have never had to do it to this point.
Code:
quiet splash intel_idle.max_cstate=1 ipv6.disable=1 cgroup_enable=memory,cpu,cpuset swapaccount=1 usbcore.autosuspend=-1 isolcpus=2,3

Peter, Thanks for the feedback on the use of the switch and the daughter cards for additional steppers. When I figure out if I can use the ECM1 card or not I will know which way to go.

What do you think about the sysctl issue and the latency issue?

For any of the Tormach hal component .so files, when linuxcnc tries to load them they return the following error about an invalid type character.
Code:
names=doorlock: Invalid type character `1'

what does this mean?

Maybe start with a fresh LinuxCNC and standard Mesa bitfile?

I think that Tormach use a special USB IO module? How hard ./ expensive is it to not use that?

I actually think that is the way I am going to proceed. I will just use a 7i76e and a 7i76 connected to an expansion header. Rewire the stuff that will remain standard on the Tormach and then add the additional drives, replacement spindle drive, etc to make this thing happen.

It looks like the Tormach Pathpilot software is made to run with LinuxCNC 2.7. None of the .ini files use the joint sections they are only using axis sections. This may have something to do with the compatibility issues i am having between LinuxCNC 2.8.1.

I think a fresh install with the standard LinuxCNC 2.8.1 build will be the best option for this machine.

I was hoping to use the tormach operator console. It looks like that won't be possible as the pins to access the controls on the console are built into the Tormach Pathpilot GUI and connected in a postgui.hal file. Since I am not able to use Pathpilot for this application those pins will not be available in LinuxCNC.

Now that I know the direction I will be heading, it is time to get down to business and actually start doing the work.

Thanks for the help everyone. I will probably start a new thread showing progress and what we are doing with this machine.

I think it is worth asking in the Pathpilot section , there is a fair bit of expertise there, but they might look in this section.

Adding a 7i76 to your 7i76E is an expensive way to add more GPIO. I would suggest starting with hooking something to the smart-serial port, such as a 7i84.

Hi, I wanted to check if there's any update on your project? I'm also planning to overwrite PathPilot with LinuxCNC so I can use the Python interface. Any updates are appreciated!

I do have updates. But I am afraid that my path is probably not the path you will want to take. I am removing the Tormach ECM interface board and replacing it with a 7i76e. This means rewiring the machine. If you want to take the same route I should be able to start posting some info in another thread soon.

Cool, but why did you decided to do so? Is the Tormach ECM no longer compatible with linuxcnc?
