Strike CNC (My first CNC router)

It's not easy when someone attacks your product on a web forum, I used to get a lot of that.

You can't tell them to go forth and multiply so you have to apply the old maxim, "Don't feed the Trolls".

Jazz isn't actually a troll, he's quite cuddly once you get to know him. I think he's just forgotten to take his meds :naughty:

Certainly could have used some Meds today Robin. .

I know the feeling but I avoid meds, I've seen too many people rot their brains. Thanks for not being cross with me

Is this particular pudding over egged, under egged or just so? We won't know until he switches it on.

Do we have any cutting specs? What kind of tolerances and feed rates are we looking for?

Hi Robin,

I won't get chance to do anything with the machine for another week or two. As soon as its up and cutting I'll post a video and details on here.

Ideally I'm looking at cutting at 2000mm/min with 5mm DOC with 8mm dia cutter in MDF. I'm building loudspeaker cabinets and not space shuttle parts so for real world tolerances on parts I'll be happy with anything better than +/-0.2mm.

Hey folks. After a spell of disappointments I've been wanting to update this thread with good news for awhile now

Its a long and probably not that interesting story but the original machine had issues with flex and play in the Z axis. With the help of JazzCNC(thanks mate) I found out the causes and took this information back to the manufacturer who did the right thing and agreed to rebuild the gantry. We stuck up a deal whereby they agreed to upgrade some of the gantry components because of inconvenience caused and I paid extra on top for them to use heavy gauge 200x40mm extrusion. You could argue that it should have been built like that from the start but I'm more interested in cutting now rather than questioning manufacturer build decisions. The important thing is its fixed and looking good for materials up to aluminium.

Jazz is sorting out some changes to the way the X axis ballscrews are mounted and I've still got a bunch of odd jobs to do here and there but I reckon it'll be cutting its first part within the next couple of weeks.

I've attached a few shots of the new gantry. Compare these to the original posted on page 4 of this thread. Looking in much better shape now.

Now there's a surprise. Lets hope StrikeCNC do better with future machines.

Well that's it. They did fix the issues and added a bunch of extra's on to the machine for the hassle. Building two gantrys surely wasn't much of an exercise in maximising profitability so I'm sure they'll learn from this and use it to avoid similar situations.

I don't really care about it now to be honest, once its up and cutting I doubt I'll remember at all.
