I am completely fed up of turning down jobs for laser engraving glass pieces.

Over the last year we've let go more than 6,000€ worth of glass engraving jobs because for some reason I cannot get my 5W UV laser to replicate what everybody and their dog are doing with theirs.

We've spent a significant amount of hours (and I mean hundreds of hours) of actual job output with plastics, marking metal, wood and plywood. HOWEVER

We cannot get to mark glass. The support guys tell us to try this and that parameters, but all we get to do is not repeatable. We waste 2 glasses to dial in, get one done, and the following one is already having shy and faded areas which results in another testing glass. Basically we have to throw away 1 for each one done.

Again, for other materials, we nail it, we've got to the point of almost zero wasted material,but glass is a complete nightmare for us.

Today we've tested settings recommended by support:

s:150, i: 0.04mm, q1, f50

Other settings from users in the community:

s:300, i 0.03mm, q1, f40

our best settings are currently:

s:80 i 0.006 q1 f33

However, this easily results in cracks.

I would really appreciate suggestions. I'm considering switching to the CO2 we have for glass. It may result in lower quality finish, but at least we can accept orders.

I've been with OVH for more than 20 years now, with personal and work accounts. Gone through outages, fires, blackouts, but this is the time I've felt genuinely deceived by them.

I decided to make the jump from our current VPS2023-Le4 (4x AMD EPYC vCPU, 4GB RAM) to a "current" VPS2026 8 core, 24GB RAM server.

Placed the order, got it installed and I found myself with a Haswell generation CPU. I think, hey it must be some CPU model exposure by KVM, this can't be happening. It clearly says VPS2026...

Well, PHP output per core was 43% higher in the previous 4 core VPS than the 2026 8-core model.

Memory is slower, NVMe throughput is slower, 8cores throughput from varnish is only 13% higher with double the cores.

I have requested cancellation of the server just a few hours later, but it says it does not give the right to get a refund. Unbelievable.
