@milad

I am considering purchasing the OpenBuilds BlackBox CNC controller as I have been using other controllers which have limited support.

Please see a link below to the documentation for the controller's spindle control:

https://docs.openbuilds.com/doku.php?id=docs:blackbox:connect-vfd

Could SOLO be used with the controller, based on this type of connection?

Thank you.

Regards,

@GS76

@Milad,

I see the link still did not work.

Please see the PDF of the page attached.

Thank you

@gs76

At analog input of S/T on SOLO UNO, you can only apply a maximum of up to 5V, it seems this module can generate various voltages up to 10V, so you need to somehow put the max speed of your motor in a way the module generates 5V, surely before connecting that output to SOLO, first you need to measure the voltage with a volt-meter and make sure it doesn't exceed 5V.

let me know if you have other questions.

Milad

I have asked the manufacturer of the CNC controller if there are other options and they think the "PWM" option may be possible.

Please see the attached document in the highlighted section in "2g" of the CNC controller's documentation. Do you think this may be an option?

Hi @gs76,

The highlighted section says the module supports a 5V leveled PWM pulse for the output, so if the desired speed is defined by the duty cycle of that PWM pulse, then it will totally match with SOLO, meaning that if the speed increases we are expecting to see some increase in the PWM duty cycle and vice versa, the frequency of the PWM though can be any thing greater than 5kHz, let me know if you need more information.

Thank you for your reply.

I will check with the CNC controller board manufacturer if their specs match your requirements.

As per our previous communication regarding using a PWM output from a CNC controller to control the analog input S/T of the Uno to control the speed.

Could you tell me how the connection would be configured with UNO, i.e. would it be connected to the S/T and ground somehow?

I just want to understand the connection.

 

Thank you again.

Hi @gs76,

Posted by: @gs76

would it be connected to the S/T and ground somehow

Yes, you just need to connect the PWM output of your CNC controller to S/T input of SOLO, besides you need to connect the Ground of your CNC controller ( the GND ) to the GND of SOLO on the same port that S/T exists ( the green 5 pin Pheonix connector)

Let me know if you have other questions.
