The machine frame is very solid, although it is made from metal and plastic parts. The linear rods are 10 mm in diameter, not 8 mm like the ones from 3D printers. It uses a custom made ATmega328p based control board running GRBL 0.9j. I like that it has an offline controller which allows me to load Gcode from SD card and keep my computer away from the CNC. In the product description, they say you should not upgrade to GRBL 1.1. I did that and the CNC works smoothly (I flashed the precompiled GRBL 1.1h using avrdude - the board has Arduino bootloader). After flashing new firmware, all settings need to be checked and set back to machine defaults (which you should get before updating firmware). By default, mine came with inverted Y axis (see the mirrored text on the red plywood). This can be fixed by sending $3=2 to GRBL (setting is saved in EEPROM and is stored even after power off). Another thing to mention is that you should double-check all screws, especially the ones from pre-assembled Z axis and spindle. My Z-axis lead screw slipped from motor axis, the spindle couldn't be lifted and I broke the bit. Spindle motor RPM is another unknown thing about these machines, and I'm thinking of measuring it. Last, use a grease spray and lubricate lead screws and linear rods. It is also important to keep these parts clean.

D1rTy_H4rRy_GR Thanxfor your review. You are pointing out some interesting things. I would like to ask you how do you get the backup of the default settings, that you set again after the upgrade. Also I am having problem with setting zero Z. In in grblcotrol and UGS, as soon as I send a job, the Z count goes to machines default and not the set one. Is this a bug of 0.9j?

An help will be appreciated.

OneTransistor @D1rTy_H4rRy_GR To get the current configuration of GRBL send $$ in Candle (grlbControl) or UGS console. The machine will send you a text report with all settings. Keep this text for later. After upgrade send $$ again and modify all settings that need to be modified (for example send $3=2 to set parameter 3 to value 2). I wrote a post about this on my website (onetransistor dot eu). There is no bug in 0.9 regarding Z axis. maybe your job gcode contains instructions that alter Z or attempt homing.

OneTransistor @BG349125133 Da, coletul a ajuns în stare bună, în 8 zile, cu Packeta de la Praga la Oradea, apoi cu Cargus de la Oradea la domiciliu. CNC-ul este demontat, dar bine ambalat. Singurul ansamblu montat este axa Z, cu motorul, dar și acesta trebuie verificat. Mie mi s-au desfăcut șuruburile în timpul lucrului pentru că nu erau bine strânse. Recomand aplicarea de adeziv fixator de filete pe șuruburile cuplajelor de axe (Loctite 243, Bison Lock Bond).
