Out of Order

Machine is tested and all the basics seem to work, we've brought it on site, cleaned, tested, and tried to document, but documentation on using it safely is incomplete. Aaron and Buzz are OK with people experimenting with this tool for the purposes of testing it out and documenting it, so long as u ask first.

20/12/2020 buzz / aaron

This machine requires induction.

Induction TBD

documentation so far mostly by Buzz and Aaron, please help us… Machine Specs: working area : 1400x900mm output power: 80W type: C02 model: PN1490 manufactured year: 2010 1250W reported total power consumption without chiller or air blower.

install SmartCarveInstall4.1.38.exe from the installer file that is available from aaron, buzz, or the digifab discord channel.

be sure to install it in English when prompted, not 'chinese simplified' .

connect usb cable to computer and be sure that it shows up as a FTDI usb .

if the COM number ( eg COM42) is above COM8, then u may need to adjust your computer/s settings ( lmgtfu) so as its in the range COM1-COM8

the installer creates a white desktop icon called “SmartCarve4” , run it.

if you get 'serial port open error' then be sure usb for laser is usb plugged-in. and turned on.

'STOP' button on laser hardware to reset machine

installing it..

desktop icon to open app…

main app window:

Tools→Config Menu: (please set this to 1400×900 at first install, as thats the working area of the laser)

File→New Menu:

file→Import → DXF … Menu:

file→Carver → Out Menu:

… carver → out → Path Optimise ….

… 'Find Com' → 'Carver Out' …

installing software part 2….

get inkscape for windows here: https://inkscape.org/release/0.92.4/windows/64-bit/

tested with version 0.92.4

Use the 'machine operation' screen do the following:

be sure you are connected first with the 'read machine→excuse' process above.

'select axis' , choose 'X' to move the head left-right

'select axis' , choose 'Y' to move the head front-back

type a number into the 'Move' field, such as '100' fto move it 100mm.

positive numbers move it toward the operator or to the left.

(0,0 is top-right)

no need to change the 'power' or 'speed values

press 'excuse' to execute movement.

repeat as necessary

Jogging mav also be performed from the button/s of the machine…

left, down, up right arrows can jog machine around to temporarily move head out of the way while loading or unloading material. ( this is not the way to set the 'home' right now.)

Using the 'machine operation' screen do the following:

be sure you are connected first with the 'read machine→excuse' process above.

manually jog machine using the app and usb connection, (not the laser arrow buttons), to the position you want to call 'home', see first set of 'jog' instructions above.

press 'set current point as anchor point'

machine should now return to that point as 'home' even after a reboot.

you can use the 'read machine→excuse' function to read the exact X and Y position in the read-only fields in the lower-right boxes of the screen.

NOTE: we don't know how to make the 'set the data coordinate' and 'set the new return point' areas of this screen work right now, and recommend NOT using them for now, as sometimes it causes serial crashes. /…?

in inkscape, set document size 'custom', width=1400mm x height=900mm (laser bed size)(see Pic.1), To increase scale of job use the scale in toolbar above drawing(see Pic.2) Pic.1 Pic.2

…or the alternate method for crappy scaling inside the 'smart carve' software , is that when u open it for the first time it asks what DPI u want to use (it defaults to 1016 dpi and is usually left on that value), but u can make a file that's already a .plt file bigger by making that value smaller, eg setting a dpi value of ~101 will make it around 10x larger that it would have otherwise been.

load a dxf, ( or jpg, bmp, or any of the supported formats) into the app - if it won't read the file, try using inkscape to save it as a dxf as that is tested.

use rectangle tool (little rectangle on the left side of the screen) to select entire printable area around job, by dragging around entire area. ← IMPORTANT

right-click area and choose 'add pen', say 'ok' after pen added ← IMPORTANT

(optional right-click and 'whole operation' …? and check pen setup - this is the page )

right-click and choose 'carve out' , or use the 'operation ' → ' carve out' to get to the same screen.

… on the 'out' screen (choose 'output group') , 'process' , then 'output' , then 'out' .

laser should start moving.

opening the front lid pauses job.

press black/red oval shaped [STOP] button on machine, NOT the big round yellow/red 1)

machine will appear to do nothing for a few seconds, but no need to hold button, and

machine will restart in a few secs.

install interlock

pull all the useful info that mike ando mentioned in discord that probably need fixing and move it all into this todo list.

buy distilled or demineralised water for chiller - Mike has bought 10L, $7, will drop off when he’s next in

find/buy usb hub for permanent install , as laser+mouse+usb-key is too much for little laptop.

buy install purchased new lense/s and 3x miror/s for spares, current cleaned mirrors are unknown age and will do for initial low-power tests, but should be replaced at some point. old lense in head is known to be particularly badly scratched and could crack soon,, keep an eye on it for now.

realign mirrors post cleaning. pre-loved mirrors/lenses were aligned on jun 17 by buzz+aaron well enough to run/calibrate/test machine, but probably could be finessed some more.

opening the front lid pauses job, so we know the switch on this door works. ..

remove,clean,reinstall mirrors x3 - 22mar 2020, aaron and buzz (undo silver screws with springs, NOT brass knurled knobs)

remove,clean,reinstall lense x1 - 22mar 2020 aaron and buzz
