Yeah I have had it up and running for a bit now! Had a few * * * * ups! Steep learning curve! Couple broken cutters and work pieces!
To be honest the cutters weren't my fault!
I have found out that at about 6.30 every night we get a power surge which sends my CNC of on one! So it just does what ever it wants to do! TWICE! At same time it was drilling 4mm hole with a 4mm bit it decided not to pull up just started to move towards the front and snapped my bit. Very frustrating especially I had no bits left and still had to drill 200 more holes.
So now I make sure I power down at 5.30 and ill start back up at 7 depending on what I am doing.
Ill post some pictures and vids later they are all on my phone but my phone is broken it doesn't hold charge so has to be plugged in constantly.

Do you have it on a UPS with power conditioning? They aren't real expensive compared to broken bits, ruined work pieces, and missed deadlines.

Well I am looking into it a bit because I spoke to a company who own a XYZ cnc and he had his machine suddenly bore into its own body, he quickly got a meter reading and found the power supply was out of the allowed tollorance so contacted the power company and they had to repair his CNC. He told me power companies must keep/maintain a steady power supply if not you tell them to do something about it because if it causes damage to your property they have to repair it.
So I might contact them and ask them if something can be done.
He told me they tried to tell him he should have what you said UPS to protect his equicpment and its his problem but he said thats a bile of crap they MUST supply a steady supply and if it goes out of bounds its their fault not yours.
He had a new CNC bed and cutter from them in the end.

I agree that they are likely contractually liable to provide service within certain bounds. The problem is that when it negatively impacts your business, machine(s), and temperament, those are hard to recover. Even if all is eventually paid for, it's a serious hassle.
Perhaps you can get them to put a power conditioner at your drop?
I have a friend who had real problems with mobile phone reception at his house and after much back-and-forth with the service provider, they gave him a "personal" transceiver to put in his house. Effectively, he had a cell tower in his living room.
Good luck!

Sounds like AT&T Microcell. I bought the first generation even though I heard that if you complained you might be able to get one for free. Without it I wouldn't have cell phone coverage at my home.

Thanks for the update would be good to see some of the stuff you have churned out and hear how having a CnC has changed you workflow... If it has?
I wonder whether your surge is JCB related, is that when they stop working.. Bit change in demand as they shut stuff down messing things up. Same time 7 days a week. If there is a pattern should be easier to resolve, they should be able to monitor from you substation what is happening

Yeah, You see I wasn't thinking of going down all the legal route just want to ask the question see what they say or what they might do. No harm asking I rather they did something then me going of spending more money again and at the moment rather tight on.
I do agree the hassle and damage it can cause me I was lucky when it happend the third time I was watching and I hit the shut down switch because the Cnc was on a collision course with the tool changer at high speed with no signs of slowing down.
that's when I decided something was up because I thought it was odd it kept happening at a certain time.

Yeah it is JCB I'm 100% sure. It happens at same time and I think its when they change shift.
When I spoke to my Cnc mechanic when my Cnc went funny the 3rd time he told me must be a big machine or multiple machines powering up or down. He told me to take note and avoid using the Cnc at that time.
Yeah CNC has helped me out...well a job I had for a company went else were because they wanting it all to be CNC'ed. They kept asking me if I had my Cnc running and then eventually stopped ordering from me. I thought they didn't need any more. Any way when I finally got my Cnc up and running I contacted them to see if they still wanting more. They told me they wanted to carry on using me but wanted things CNC'ed so they used another company who had a Cnc.
Any way little later they contacted me and made £9k order so with out the Cnc I wouldn't have had that job back and hoepfully an on going job.
It has helped me with many small jobs which I thought I wouldn't have used it for
It's not used as much as I like it to be but that's also my fault because I'm the only one who can use it and I'm 60% time not at the workshop.

How is the CNC wired, is the controller and stepper motors independant of the spindle and vacuum pump. I imagine the vacuum pump probably uses the most power, followed the the spindle, then the stepper motors and computer. In terms of surge protection or power conditioning, the spindle and vacuum would be the least effected/ if at all. The computer is probably ok as well, I suspect its the stepper controller or the stepper motors that are being impacted.
Given its at the same time each day the power company should be able to come and check/confirm the surge. Surge protects won't help much as they will just cut the power, its more power conditioning you need, but I think that gets pretty expensive as in effects they have the buffer the incoming power, regulate and then feed.

You are totally correct! I remember him saying something about conditioning and he said it's not cheap.
It all kinda went over my head because he was talking more in electrical terms and I was getting little lost.
