I've been given two CTC 3D Printers that look exactly like the one in this link https://www.amazon.co.uk/CTC-Extruder-Upgraded-Pre...

The problem is, I don't really know what I'm doing.

I've plugged both in and there was an SD card in one of them. I've levelled the beds and I've done some tests printing something from the SD card on both printers. Both printers appear to be working fine producing similar (but not perfect) results.

The problem I'm having is these printers seem to only accept x3g files on SD card, but I have absolutely no idea what software I can use on my Mac to load downloaded models and then export them to x3g. I've tried the latest Makerbot print software, but it no longer exports to the file type I need.

For context, I'm a software developer so I'm fairly technical, but there seems to be a huge array of information online and none of it seems to help me.

Also, any comments on these printers? I can see they're about £270 new on ebay, and I believe they're meant to be old makerbot clones? While I'm sure they'll be fine to mess around with, I have no idea if they're any good or not.

I also believe the beds on these printers originally had a gold foil over the top of the aluminium bed, but it's no longer there, where can I get replacement adhesive foil?

Any assistance would be appreciated.

An expert will be along shortly, but I think X3G is the format the Cura slicer software uses (available for Mac, Windows, Linux).

Thanks. I tried that software but it doesn't seem to support X3G exports.

I wonder if there's an option to upgrade the firmware on the printers so that they can support other formats?

EDIT:

Actually, it looks like if I export to .gcode the printer is picking up the file.

Doesn't look like Cura exports in that format but if gcode is working use that.
Some quick googling makes it looks like they need a lot of fettling to get up to 'ok' standard.

One thing I've just noticed. Only one of the printers will accept the .gcode file type.

Both printers seem to be running Pro Creator v1.0 firmware. Strangely one of them shows as having two nozzles and the other only one nozzle.

Slicing software like Cura of PrusaSlicer(Slic3r?) convert .stl files from places like thingiverse, into .gcode.

The files on your SD card I would suggest can't be opened by Cura or Prisaslicer because they've already been sliced.

So you need to find the file you want to download, load in into slicing software, and slice then save.

If your printer doesn't work with .gcode then the above is obviously useless, but I would try Cura as suggested, to slice a downloaded .stl, and see if the printer will read it from the SD card.

Just to be clear, the finished sliced file is different to the file that you can save before slicing - the pre-sliced file is usually saved as a 'project'.

Yours seems to be a makerbot print file, made from an imported STL.

In Prusaslicer, this is saved as .3mf

Thanks.

I understand that the project file and the sliced file is different. The issue I have now is that one printer reads .gcode and the other doesn't but both seem to be running the same software.

I fixed the dual extruder issue, there was a setting to enable it.

Are they both running the same firmware version?

As far as I can see yes. They both startup saying Pro Creator v1.0.

I've ordered a printer cable as I want to update both firmwares anyway, so maybe once I've done that it'll fix the issue.

I've got one of them printing a rocket ship at the minute, but I'll double check it's firmware in the settings when it's finished.

You might be able to pause the print and dig through the menu then restart.

I'd guess they originally had kapton tape on them - easy enough to get on eBay, I'd say get the widest you can to save time fitting it. Many tutorials on how to get a bubble-free fit with soapy water. I use green painters tape nowadays.


Edited: caveat that the soapy water approach to getting a bubble-free kapton base worked fine with the removable glass beds I used on my old RepRepPro machines, if your aluminium bed is fixed in the machine then it may not react so well...

Thanks.

Ive been using blue painters tape that I had in the garage today, and it's worked well.

I checked, both running the same version of firmware.

I put the SD card from one machine into the other, and it's reading the .gcode file perfectly fine. It seems to be SD card related for some reason.

Sorry. Ignore me, neither printers support gcode files. I must have already had the same file on the SD card as an x3g file.

So Cura is no good for me.

EDIT:

Found a Cura plugin that allows exporting to x3g

I found an instructables on how to convert gcode to your format.

Here you go. https://www.instructables.com/Gcode-to-X3g/

The plugin to create x3g files don't seem to work on the printer. When I select the file I just see the nozzle/bed temps and nothing happens.

I must be doing something wrong. I've select the printer to be a Makerbot copy and checks the dimensions are correct. Tried multiple files as well.

Thanks, the problem is replicator g doesn't seem to be available any more.

If I was you I'd get that second printer running as well as the other one and sell them both before they stop working. Get your hands on a Prusa Mini and yes, there may be issues but you'll be able to resolve them quickly due to the huge community, and it'll be a lot more reliable than anything else at that price point.

Apparently tinkercad can export to x3g ? https://tinkercad.zendesk.com/hc/en-us/community/p...

I wonder if you could find a firmware that accepts gcode that it would run.

I found something called Flashprint that works on Mac and exports to x3g, and it actually works.
