[Resolved] Need help with the XYZ Probe Plus / Grbl Error 9 - Alarm: 4

Ok peter
I understood, this is what I planned.
Apart from using the ferrites I have to provide an individual Earth Ground for the whole cable circuit of the machine or can I connect to the domestic Earth circuit?

 

Thank you Peter, excuse me but what does "PE Screw" mean how to recognize it?

 

So sorry thanks (problem with some abreviations)

 

Hello everyone,
Here the fight against the EMI does not progress, the machine works wonderfully with the PC (wifi connection), when I connect the Interface to BlackBox and I start the system all the functions are Ok, but Interface and CNC becomes completely crazy as soon as I start the Spindle!

Since my last intervention on December 22 I have made the following modifications on the wiring:

• VFD is in Earth
• Deported the Spindle cable out of the chain and in Earth, the cable is now suspended above the machine
• Connected Spindle's body to Earth via the Gantry. Gantry is also in Earth.
• Connected the 0-10V cable shield from Blackbox to Earth.

Received this morning and installed the ferrites on all the cables:

• Blackbox input and interface
• Input and output of the VFD cables

The CNC is not in a very easy place and at my feeling The VFD box is still too close to the machine and electronics (50 cm.), I could place the VFD box in a place where I would need 2.5 meters For the Spindle cable and 3.5 meters for the 0-10V cable.
I have no choice if I want a distance between the CNC and the VFD box.

Questions:

• Is it possible to have long lengths with the 0-10V cables and the Spindle cable?
• What maximum length for the 0-10V control cable between the VFD and Blackbox?
• What maximum length for power cable between the VFD and Spindle?
• What minimum distance between the VFD case and the electronics control (BlackBox-Interface)?
• What minimum distance between the Spindle cable and the 0-10V command cable?

That's all I can say for the moment because I have no skills on HF solutions.

If you wish I can also post photos on the work done.
Thanks for reading me!

 

Thank you Peter for these details, depending on what you say I will try the solution to deport the VFD box and change the 0-10V cable for a longer (also with shield, like the previous one).
I will also remove the Earth link between the Gantry and the Spindle body and deport the Earth to put the central point inside the VFD box.
As you say, the possibility of changing router is also a good idea that I considered, I have a Makita RT0700C router and also a Bosch Pro GKF600 router that I can also install. The first problem is that these machines are very noisy, and second problem, I would lose the management possibilities available with the Blackbox X32. I do not envisage this idea at the moment.

 

Thank you Misterg,
According to the @Peter Van Der Walt recommendations, I will deport in another place the case which contains the VFD. This topology will allow the VFD to be plugged into another outlet in my workshop.

Thank you for this track.
I'll keep you informed of the results.

 

Hi misterg
What components should the filter be installed?
Psu > Blackbox?
VFD?
All?
The PSU Openbuilds has an integrated filter already I presume?
The Socket Wall Power Cable > VFD must be with shield?

I suppose that the filter must be between the home sockets and the component to protect PSU / VFD!?

 

Ok, next step ... never ending shopping continues.
- 1x power bar with HF protective filter and integrated overvoltage protection.
- 2x HF 220 V 500UH filter
- 1x 230 V / AC rotary switch
Thanks for helping

Hi Peter,
Considering your suggestion about the CNC RoutER11 kit.
How to automate the start and stop of spindle as well as control of the rotation speed?
In the event that I want to use another machine to do other types of work and also supply with spare parts (brushes), be able to consult the user manual before purchasing because I did not find any relevant information on this subject on the Internet.
Thank you for your information and your help!

 

Thank you very much Alex but I see that this relay cannot be supplied with an AC 220V power

Hi
What do you think of this wiring for EMI filtering [EDIT Bad wiring replaced by new]

 

Hi, @Peter Van Der Walt @Misterg
Thank you for your recommendations I went to see the information on https://www.motionControltips.com/Problems-vfds-CAUSE-COPLEPES-HELP-SOLVE/
I also found a link that relates everything you have already informed me in our discussion EMI Filter Installation Best Practices | EMI Filter Installation.
Modified wiring scheme and will delete the old and put the new one so as not to leave bad information in the thread, give me your opinion that will allow me to know if I understood you well).
I received and installed the power bar but it doesn't change the problem.
Tomorrow I would receive the filters (I had to order 3 to be delivered, but no problem I will keep them in reserve ... it does not eat caviar
***********************************************************************
I must mention an important thing about my 0-10V VFD> bbx32 control cable; This is a cable that I use for video surveillance and access control, is double shielded (4x 0.8 U72 HF mm. Rigid), it is 1.70 meters long (5.6ft).
When I put my VFD under tension the Spindle runs at 1600 RPM without instruction in the control software for startup.
This has occurred since I deported the VFD in the box which is now on the opposite side of the X32 and the CNC, which I had to increase the length of the 0-10V control cable which connects the VFD at the X32.
Previously for reasons of practicality and cabling comfort The X32 and the VFD were located on the same side of the CNC, the control cable measured 60 cm. (2.0ft) In this configuration I had never had a problem.
***********************************************************************
My case is a reference in terms of debug or have you had similar situations before?

In advance 2 pics to see the situation

 

Yes I have to see the RPM Min & Max again so that the Spindle does not start below 3000 RPM (I must be too low with my minimum setting, with the old cable of 2 Ft that had never happened, I do not has no response to this anomaly.

 

Certainly, tomorrow I have to dismantle the box and completely redo the wiring with the new filter and put the cables and shields in star on the plate

 

Yes I have this model A2-8015.
The connection to the BBX32 is below
