Right, probably was included in the available libraries because time ago i was sperimenting with a teensy controller.
The encoder library is from here:

@kevinallen1902200 I'm planning to build a PrintNC router this winter and power it using duet closed-loop steppers. You might be interested in joining the printnc discord, I know a few people there that are discussing milling machines

@Valveman you can do if you like

Having great success using LightBurn to create a path for fly-cutting a thin layer off the sacrificial table.

@tomtendo I expect because you had D0 and H1 in your M563 command, which don't exist, it was causing an error and not being processed. Also the R0 S0 in your M568 command refers to temperature. You can use M568 F parameter for spindle speed, see https://docs.duet3d.com/User_manual/Reference/Gcodes#m568-set-tool-settings

I connected without using Panel

@o_lampe no, it's the crossing point of the three last axes of the industrial robot. The calculation of the inverse kinematics is much easier when they cross. The nozzle will simply add with his length and orientation.

Just wanted to update to say I've been using daemon.g to control my VFD over modbus for a while now and it feels like it's working well. The error messages not being suppressed when writing to a variable is a bit of a pain but aside from that, it feels like a relatively robust way to do it.

For clarity, I still have the spindle configured to use enable / direction / PWM pins but these are not connected. I read the spindle state in daemon.g and send the relevant Modbus requests to start it and control the speed.

I've had a 2 second comms timeout set on the VFD so if there's no Modbus status check within 2 seconds the VFD will stop automatically.

There's a lot of functionality I could add to this to e-stop / pause / whatever if the VFD reports the spindle stopped or at high load or is completely unresponsive, but for the moment I'm pretty happy with the behaviour.

@gloomyandy said in MQL System with Diesel Heater Pump:

@NineMile Have you tried doing 1-5Hz just using M950?

I have a basic implementation of this now that uses M950 for anything equal to or over 1Hz, and then for anything lower I use daemon.g to run the on/off cycle, which seems to work nicely.

@dc42 Thank you. The math looks good. I will try it out.

In the mean time I used a couple blocks to align the part to the x and y axis and then found zero using the edges of the part. It would be great to have a macro that allows you to place the part/stock and then adjust the machine using the edges without having to do the manual alignment. Assuming you have a couple straight edges perpendicular to each other. Another handy thing would be a macro to flip the part if you need to machine both sides of the part. Is there a G code that allows you to mirror one of the WCS axis?

Hello everyone,

I have a water-cooled spindle and would like to implement the following scenario:

When I turn on my spindle with the M5 command, my coolant pump (24V) should automatically start to cool the spindle. In addition to controlling the spindle speed and turning it on and off, I want to turn on a pump as well.

It is important that the coolant pump continues running for about one minute after the spindle is turned off (M5), before it completely shuts down. Is there a way to implement this with some logic or an output signal?

M950 R0 C"e0heat+e1heat" Q1000 L24000 ; Configure spindle on e0heat + e1heat, PWM at 1000 Hz ; Tools and Spindle M563 P0 R0 S"Spindle" ; Define Tool 0 as spindle G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets M568 P0 F6000 ; Set tool 0 default RPM

Thank you in advance for your support!

@droftarts Thank you for your opinion.
I tried to that and the machine did no longer crashes.

I changed the Emergyency stop configuration to external trigger.
As a result, the external trigger was triggered while homey.g was runnning.

So, Maybe the emergyency stop button and something are interfering.
I'm going to search the causing.
Thank you droftarts!

@morgoth90 See the Ooznest documentation. They plug it into the E0 endstop input on a Duet 2. https://learn.ooznest.co.uk/Guide/Assembling+Your+Original+WorkBee+XYZ+Touch+Probe/61#s309
So any free IO header on the 6HC will work fine, wired as an endstop. You may need to define it as a 'Normally Open' endstop, ie with pin inverted with !.
Yes, M675 uses the same probe for all axes.

@Valveman See @jay_s_uk's post earlier. That's all you need. I was just explaining what it actually does.

Ian

I did it. The solution was actually very simple, so I'm wondering why I didn't figure it out much earlier.
