So that is at least two axis on opposing sides sometimes doing arcs simultaneously...

It is not possible to execute two arcs simultaneously. What you could do is use the switchable kinematics feature to switch the X and Z axes to different joints. So you could run regular gcode with arcs in the XZ plane and switch in gcode on which side of the work piece the movement takes place. Remember though that this is possible only one after the other not both simultaneously.

Arc moves are really only defined for linear axes XY, XZ or YZ. If you need different linear axes to perform arcs then switching the joint/axes mapping using switchable kinematics seems to be the only way to go.

When HOME_SEQUENCE = 0 I'm thinking of running a subroutine at startup, I'll equalize the axis positions there, for example I'll send the y1 axis to the y2 axis position and then
Maybe changing HOME_SEQUENCE =-2 could solve the problem. but I don't know how to change these parameters in gcode file
I want to change the HOME_SEQUENCE parameter for joint_1 and join_2. But I will try and see if this is a solution.

I have done many tests but the problem persists. If the two engine positions are not the same at the first start, one of the engines tries to move to the other engine's position very quickly.
I have no idea how to solve this

Hi..thanks for reply..on a wood lathe I would have rough cut on one side opposed on other with finish cutter...both would need to do arcs but at slightly different times ..also finish cutter acting like skew would have to reverse while rough waits and the both move forward again though offset slightly still. So that is at least two axis on opposing sides sometimes doing arcs simultaneously...finish cutter actually has another axis to rotate cutter to keep bevel angle to wood....would using angular instead of linear work?

Thanks again,
Rick

hello everyone
My self-made EtherCAT IO controller chip is LAN9252, which comes with 16 GPIO. I want to use the SSC tool to create an XML file with 13 GPIO inputs and 3 GPIO outputs to flash onto the PCB board, but I don't know how to use the SSC tool. Can any expert teach me?

Nice to see another Maho, and a MH600T at that. I am also in the process of converting mine to LinuxCNC:
forum.linuxcnc.org/30-cnc-machines/49758...mizing-a-maho-mh600t

Do you have the schematics for the MH600T? I have been working off of MH600E schematics I found online. I don't think they should differ too much, though. But if you have MH600T schematics, I sure wouldn't mind a copy.

Did you manage to fix the issue with the hydraulic pump? From what I see in the schematics I use, only the hydraulic pump overtemperature switch should be involved in the machine power/e-stop The temperature switch is 3B1 is needed to pull relay K1, which in turn is needed to "turn on" the machine by latching 7K1.
 
 

I want to use some GStat messages in a Glade VCP (in gmoccapy), but it seems that not all messages seem to work there.

If I take the example from linuxcnc.org/docs/2.9/html/gui/gstat.htm...tension_code_pattern everything works as expected.
Then I added

The result is that I only get the message resp. signal when a new file is loaded, not on a reload.
But if I add this signal in the gmoccapy code directly, I get an event on every reload.

Furthermore the signal "graphics-gcode-properties" works fine inside gmoccapy, but in a VCP I don't get the message at all?

Any ideas about this behaviour?

As far as I know arc moves are only possible in XYZ. Maybe you could describe your setup in more detail as there may be another way to get what you want.

Hi again.

After some testing, I can say I have had no more program interruptions. I've been playing around with the max velocities and accelerations of each axis and joint to find a sweet spot where the machine does not produce those unpleasant vibrations and knocking noises. There is, however, something still weird about it.

When running LinuxCNC and even some light app like a file manager or something, everything is in order. This may sound silly, but whenever there is a terminal open and I am interacting with it, the vibrations happen. So much so that when I have for example my .hal open in vim in the terminal and I use the mouse scroll wheel to navigate the file, the vibrations are in tandem with my scrolling of the wheel. Extremely weird in my opinion, yet I can definitely say it's not a joke.

Any idea what could be causing this? Granted, I am not too worried, as I am not planning on having any terminal (or anything for that matter) be opened alongside LinuxCNC when the machine is in production.

PS. Could anyone help me out in making Axis GUI not set the max velocity to the maximum allowed when I start LinuxCNC? This behavior could be dangerous if someone were to run a poorly written program, so I'd like to have it set to a smaller value by default on startup.

Well, I run sensor in terminal and output is in below:

Now the max jotter is 7000ns (servo thread) and 11880ns(base thread). If any thing abnormal in above data, please reply.

I am waiting for the spike to happen again and check sensor data again.
 

wow, thank you
my ping was 0.4s to the mesa card and went to 0.4ms

Since you already purchased 7i77 boards. SC900 servo drive does already convert resolver signal to incremental signal, lucky you Connect encoder incremental wires from the sc900 servo drive to 7i77. Connect +-10vdc from 7i77 analog outputs to sc900 servo drive. You still need the enable signal from the 7i77 to sc900 servo drive. I briefly had a look at your diagrams, it looks likeJ4 Pin 6 might be useful to enable drive (You still need to determine if the enable signal needs to be high or low)

for user xaxexa, when you say one pulse output , are you referring to it as only an A channel (x pulse/revolution) or do you mean it is a single pulse like an index channel where 1 pulse/revolution ?
if it is the index channel, you could probably implement it.

Echo to Murphy, we could benefit from having the option for only A/Z as it seems common for lathe users, , Myself and other users are finding increasing need for a non quadratic option so the encoder module can be used for MPG. Using Encoder module vs DIgitial IO for an MPG is a cleaner hal file, but also using digital IO for MPG uses 12% of the available inputs on the SPI version

Dear friends im facing problem of connecting 7I77 with Resolver based brushless servo encoder, Motors is rotating but not showing position changes on display. Pls help
