Hello,
I want purchase 3d printer, i have question about T300:
-T300, are open source than other sovol 3d printer?
-Why T300 are power supply of 150W 24VDC , all other 3d printer are bigger power supply.
The only reason that is Hotbed Temperature is direct powered by the AC sector, can you confirm me?
-T300 3d printer have more or less good and stable mechanical than SV06/SV07 3d printer?
Thanks
Could you provide some answers?
First off I show the T-300 Has a 600W power supply. Allow 70 for the nozzle heater and say 80 for the mainboard leaves 450 for the 6 motors. Should be adequate but not much headroom. The bed heater is connected directly to the mains via a PWM controller.
The Mainboard has 6 motor drivers giving Z tilt function. The Y motors could be stepped separately but I can’t think of a reason you’d want to. The mainboard does NOT have a imbedded “computer” that runs Linux and Klipper. I’m a big fan of separate boards as that makes upgrades easier.
The toolhead does NOT include a MCU. Simpler on one hand but less upgradable. You’ll have to manually mount the accelerometer to do resonance testing. The toolhead does have a single ribbon cable for easy servicing. The bed probe appears to be a generic proximity switch, The rotation distance for X and Y is 72mm (40 is typical) so 1 micro step is 20 microns (12.5 is typical)
The included touchscreen appears to have the same mainboard (built by makerbase) as the Sovol Klipad50 that ships with the SV07 twins and was sold as an upgrade to the SV06. I didn’t dig deep enough to determine if the same display panel is used. There was considerable issues with the Klipad’s display not playing nice with newer Linux Kernels. Seems to be fixed now.
Makerbase doesn’t support OEM products. Sovol/Comgrow struggle with support. Plan on purchasing a USB to EMMC dongle. Much easier to “etch” an image than trying to fix things via SSH.
Overall the T-300 is a beast of a bed slinger. Never be as fast as a core XY but other than that it seems like a good unit as long as the possibility if needing to buy a Rasberry Pi + touchscreen down the road isn’t a deal breaker.
If I had a bigger work bench I’d be verry tempted.
Hi,
I correct one point, the T300 have 150W power supply (Power Supply for SV08/T300 3D Printer) and (https://youtu.be/WmzWLuvOGyY?t=2154) and the T500 have 600W (SV07 Plus 3D Printer 600W Power Supply for T500).
I dont see the problem with the main board, of Makerbase, in fact this is a computer and it have linux on it, that is same as a Raspberry Pi (https://www.youtube.com/watch?v=F4MNeVlgkNY&t=273s).
For sending image, we are not in 90’ year, but we have klipper interface, we can send it directly from a remote PC (https://youtu.be/bI0xOiKdMQw?t=129) or (https://www.youtube.com/watch?v=WmzWLuvOGyY&t=10231s)
Thanks
ALMOST the same as Raspberry. The MKSPi won’t run Raspbian. It runs Armbian (plus a couple closed source modules from MKS to get all the hardware to work).
Support for Raspbian is 10X better than Armbian.
To clarify the USB dongle is for upgrading/repairing the OS on the MKSPi not printing models.
You are correct about the 150W power supply.
If you add up the max current from printer.cfg you get 6.6 amps (148.8 W). But that is max acceleration for all 4 axis and the extruder at once. Can’t happen and if it did would only be for 1/4 second or so.
None of the reviewers had power supply concerns.
