Hello Nauris and Welcome.

Can I just say that these machines are over rated and over priced for what you get. They have some serious weakness issues in key component areas and design. Mostly because they use unsupported round linear rails on all axis.

These rails tend to flex and vibrate/resonate which affects the resulting finish and feeds you can run the machine at. The Long axis is one key point for flex because it carries the weight of the gantry and the Z axis etc. But the other key area is Z axis it's self which again uses unsupported rails and is a very flimsy weak area on the machine.
The Z axis is Key on any machine because it carries the cutting tool so if it resonates this shows in a poor finish on the material. The other side affect of weak Z axis is cutter brackage and excessive tool wear. It also restricts the feeds you can run the machine at. Weak means cutting slower to avoid resonance, cutting too slow equals poor finish and excessive tool wear.

Another poor area is that they use Acme Lead screws not ballscrews which are not has efficient and often with higher backlash.
This is high lighted by the quoted Rapid and Cutting feeds of the machine. 3000mm/min Max cutting speed is very low for machine that is mostly only any good for cutting woods and plastics. It should be double this for cutting and in the 8-10,000mm/min Rapid speed range.

To be fair thou It's not all the screws low efficiency at fault here the electronics will play some part which also indicates low spec but without seeing more I won't comment to much on this.!!

Then you have the design and accurecy to think about.? The design of these machines with just a Rectangle frame which sits directly on the table surface with no Bracing or support to avoid twisting is a Major failing. All your accurecy relys on the table you sit it on being perfectly flat and not twisted in anyway.!! . . . . Very few tables are that flat or not in some amount of twist.
The frame it's self doesn't provide any strength against twist so say for instance you happen to place it on the table and a Screw head is slightly sticking up, say 1mm and under one of the extrusion rails then your machine is now twisted by this amount and accurecy is out the window.

These areas I've high lighted are Key fundamental areas to having any decent machine and this machine fails badly IMO.
Now your going to say "Well those who have them like them" so can't be that bad.!! . . . .Yes maybe so but that's because they don't know any different and haven't used or experienced a good machine.

Sorry to be down or Negative on this machine but I honestly can't see why people buy them or pay the price they do for them given all the hidden extra's.
Now those who know me well will spit there coffee out over the screen at what I'm about to say given my dislike of what I'm about to suggest.!!!! . . . You'll be better with a Cheap Chinese machine and replace the electronics.!!

Why.?
Because they do have Ballscrews. They do have Supported linear rails. The frame is stronger with a proper bed. The Z axis is equal in strength. They often come with Water cooled Spindle that knocks the Kress toy town spindle into a cocked hat.

They are often let down with poor build quality and often cheap nasty electronics but with a little TLC and new electrics they will still beat the heiz machine in most all departments and cost less in the end.!!

Am I recommending you do this.? . . .No.!! . . I suggest buying something better than both or build your own custom machine. But I would before buy one of those Hiez machines.
