Got myself one of these...

Place your bets on how long it will be before I find something wrong with it...

As soon as it is delivered

Qu'est ce que c'est?

A reflow oven?

As soon as it is delivered

My vote is more optimistic..10 minutes..

A reflow oven?

Already got a massive oven

It's a 3D pinter..

All the things I hate in other printers... This one has that stuff fixed...so it seems....

It's a 3D pinter..

Oh lawks -- that's number two behind the AI prompt on the list of things Exxos should be kept away from!

I'm hopeful this 5th printer might work right it's got good reviews.. but then again , so did the others...

I wonder if the AI can write gcode hmmm..gonna have to go look now...

EDIT:

Code: Select all

Sure, I can help you create G-code for a 50mm square to be 3D printed. Below is a simple G-code script that you can use to print a square with a 50mm side length. This example assumes you are using a standard Cartesian FDM 3D printer with basic settings.

### G-code Explanation

- **G28**: Home all axes.
- **G1 F1500**: Set the feed rate to 1500 mm/min.
- **G92**: Set the current position to the given coordinates.
- **M104 S200**: Set the extruder temperature to 200°C.
- **M140 S60**: Set the bed temperature to 60°C.
- **M190 S60**: Wait for the bed temperature to reach 60°C.
- **M109 S200**: Wait for the extruder temperature to reach 200°C.
- **M82**: Set extruder to absolute mode.
- **G1 X__ Y__**: Move the print head to a specified position.
- **G1 Z__**: Move the print head to a specified height.
- **G1 E__**: Extrude filament.

### G-code for 50mm Square

```gcode
; Start G-code
G28 ; Home all axes
G1 Z15 F9000 ; Move the platform down 15mm
G92 E0 ; Reset the extruder's position
M104 S200 ; Set extruder temperature to 200°C
M140 S60 ; Set bed temperature to 60°C
M190 S60 ; Wait for bed temperature to reach 60°C
M109 S200 ; Wait for extruder temperature to reach 200°C
M82 ; Set extruder to absolute mode

; Draw a 50mm square
G1 Z0.3 F1500 ; Move to the first layer height
G1 X0 Y0 F1500 ; Move to start position
G1 E10 ; Prime the extruder

; Start the square
G1 X50 Y0 E15 ; Draw the first side (50mm along X-axis)
G1 X50 Y50 E30 ; Draw the second side (50mm along Y-axis)
G1 X0 Y50 E45 ; Draw the third side (50mm back along X-axis)
G1 X0 Y0 E60 ; Draw the fourth side (50mm back along Y-axis)

G1 E50 ; Retract the filament slightly
G1 Z15 F9000 ; Move the platform down 15mm

; End G-code
M104 S0 ; Turn off the extruder
M140 S0 ; Turn off the bed
G1 X0 Y200 F9000 ; Move the print head away
M84 ; Disable motors
```

### Explanation

1. **Heating and Homing**: The printer homes all axes, sets temperatures, and waits until they are reached.

2. **Starting Position**: The print head moves to a safe height, then positions itself at the origin (0,0).

3. **Drawing the Square**: The print head moves along the four sides of the square, extruding filament as it goes. Each `G1` command moves the print head and extrudes a calculated amount of filament (in this example, arbitrary extrusion lengths are provided for demonstration purposes).

4. **Finishing**: Retracts the filament slightly, moves the print head away, turns off heaters, and disables motors.

### Considerations

- **Layer Height**: This script uses a 0.3mm layer height for the first layer. You might want to adjust this based on your printer and filament.
  
- **Extrusion Values**: The extrusion lengths (E values) are arbitrary here. You will need to adjust them based on your printer’s calibration.

- **Temperatures**: Adjust temperatures according to your filament specifications.

### Adjusting for Your Printer

- **Bed Leveling**: Ensure your bed is leveled properly before starting the print.

- **Calibrate E-steps**: Ensure your extruder is calibrated for the correct extrusion values.

- **Slicer Settings**: Normally, a slicer would generate these values based on your setup, so you might want to test and tweak this manually written G-code on your printer.

You can copy this G-code into a text editor and save it as a `.gcode` file to use with your 3D printer. Adjust any specific parameters like temperatures and extrusion lengths as needed for your specific printer setup.

I guess I should have said cube

What..what.....you can do loops in gcode ?!

Wow that's half the price of the Prusa MK3S we have here at work (which I play around with a lot) but it looks much better built than the Prusa (which is mainly made of 3D printed parts and plastic)

I've been really impressed with the Prusa... I just send stuff to it, and it prints it perfectly. And the Prusa Slicer software is so easy and intuitive to use (apparently its open source and available to use for any printer... it exports Gcode)

The fact that this printer is literally half the cost, makes me wonder if the Prusa is really special?

We also have Ultimaker S5's and S3's at work too, but I'm not always allowed to use them. They're super expensive.

It looks as if the loop is left as an exercise to the reader.

Perhaps uncle AI thinks you're typing these in by hand?

New printer arrived! all 31KG of it!

Here's just a list of random pictures I took during unpacking...

@Icky was right to time to being annoyed More on that to follow later..
