Have you checked the hydraulic valve block inside the pump cabinet?

On our machine there is a primary valve assembly just inside the front acess panel. There are two components on the block...

If you want a reliable spindle for less look for a RECON unit, a recon from a decent spindle brand will outlast and outperform any brand new Chinese offering.

5hp Italian Elte air cooled spindle...

Ok, so every time you turn on the machine your software settings tell it to perform a homing operation. Homing essentially sends the machine to a default starting position- your software describes...

Have you checked the beam alignment?

You say you've changed the mirrors... did you check the beam alignment straight after? If the beam is only giving a glancing "blow" on your mirrors and/or...

150w Reci tubes won't cut 3mm steel... in fact NO 150/80w tube will even come close. These lower end tubes need a feed of pure oxygen at 2 bar to cut metal. Blowing oxygen through the cutting head at...

We've had two 150w Reci tubes replaced under warranty... carriage cost excluded.

Make a short video of the machine under power and email it to your supplier.... if they don't respond nudge RECI...

Perhaps I should clarify;

The important variables are the quality of the laser tube and the efficiency which it is kept cool..... if these two components don't stack up you are screwed- even if...

Your budget easily runs to a fairly decent Chinese machine... whether you buy it direct or with a chunky markup from a UK supplier.

All Chinese machines share the same basic architecture... it'll...

How old are your ball screws? How well are they and the drive nuts protected from Garnet?

I've seen similar misshapen cut results when the ball screw or nut are very worn- in our case garent found...

You need to change the pulse per minute for the X and Y steppers.

Take the current pulse value for x & y and divide it by 44- this will give you a figure for the current pulses per millimeter for...

Leetro/ Lasercut software has a load of settings which you can alter- from memory homing direction can be changed using P or R direction settings- essentially flipping the stepper + - or - +. These...

We run a Swedish made Vacculex jib crane and it's awesome.

Our two main machines (Jet & Router) are virtually identical in size to yours and we managed to install the crane so it'll load both...

What brand mixing nozzles are you using?

We had similar excessive wear problems, not with the nozzle itself but with the ruby just above it. We finally worked out that an entire batch of jewels...

I don't have a lot of money in my machine and don't have to make a big monthly payment for it..... if I charge the going market rate I make a BIGGER profit which I get to keep as a fatter profit...

Corel is used in our shop to draw artistic parts for our routing, laser cutting & waterjet machinery.... so yes, Corel is perfect for everything you want to do.

Corel is cheap, easy to use, easy...

You shouldn't be cutting directly on top of a solid metal plate... the bed of your laser should be either a hollow honeycomb design or it should be a series of metal strips with gaps in between.
...

First and foremost it's worth pointing out that the sample given is a Carvaggio sign blank which looks like it's straight out of a Spandex brochure.

These signs have been around for ages through...

There is nothing wrong with the Wolf file you created in Corel... I've just downloaded it and it opens perfectly in Corel x4.... in fact it's a pretty sweet, smooth vector file.

What DXF version...

or...

create a separate tool path for the holes using a 7.5mm drill bit... drill the holes, swap out to a router bit and run the cutting portion of the part.

A vinyl cutter doesn't normally need a dongle to operate properly... the missing dongle probably refers to the software the previous owner used to run the cutter.... more than likely Flexi sign.
...

Bezarc gives you these DXF options in a little menu box, you choose your preferences and Bezarc applies them every time you export out a DXF file.

We run our Elte air cooled spindles up to 8 hours a day with no problems.

If you pick a good quality air cooled spindle from a US or European manufacturer you are paying for a very high quality,...

Google- Bezarc

If you want a DXF smoother then Bezarc is pretty good.

The problems you are experiencing are not unique and will not be resolved by switching to another CAD package..... PLEASE...

Tried a USB cable?

Chances are your PC will auto detect the hardware in your press and allow you to access it like you would an SD card on your digital camera.

If the stick is full and you want...

I would use the lower limit for 4mm as the absolute maximum for 3mm cutters. This smaller sized cutter is a very handy tool.... but 3mm bits are flighty little buggers... they can snap very easily if...

No problem.

When cutting any kind of acrylic you want to be using a single flute spiral up cutter bit.

For 15mm acrylic you'll have to run with several passes; I usually do 3 5mm passes on 15mm...

Waterjet control software has a "look ahead" tool path feature which slows the feed rate automatically whenever a small radius is present. You are correct in saying this feature is used to minimise...

What's wrong with drinking water straight out of the tap? That's all we've ever used and the sky didn't fall in.

In our laser cooling system the temperature rarely rises above 6 celcius even with...

This type of sign is usually a fibreglass construction because it's cheap, strong, light and very durable in external applications.

+1 for the screws.

Cheap, easy, fast and guaranteed to work... what's not to like :)
