Welcome to the SeeMeCNC Community

I have the same problem.
Make sure that your extruders temperature is just above the setting in the gcode before you press RUN.

Hi,

I am running the repetier 0.91 software on Rambo 1.

When implementing the new firmware, I experience that I have o never ending retraction when the temperature is below 225 deg c.

Does anybody know why and what to do about it?

Thanks for the hint, however it did not help. My X Y and Z distances are correct in vertical movement, but not in the horisontal way. After upgrading I forund that the Radius had to be adjusted from the 198.25 to 162mm to get the head even along the hotplate. And this courses the horisontal movement ...

The original Rostock Perk with Rambo 1.0 I have tried to upgrade to the new version form Semeecnc download page. However, the movement of the axises are too short. By models are to small then when printed. when I move from Y95 to Y+95, the gotend only moves abt 70mm. Does anybody have a hint ...

Hi.
How do I set up the Cura so my objects are printed in the center of the Rostock. Or even better, how do I control the position of more oblects?

Tnaks in advance

For your spare list: Add also 1 or 2 of the push in fittings for the bowden tube. Mine broke last night, resulting in 5 meters of filament in the workshop. When it breaks, it is non repairable, you need a new one. Does anyone have data for this component, as I would prefer to purchase them locally ...

Hi,

I found out that the inner tube must fit exactly in the length so it cannot move together with the filament.

I have fine result with hairspray. And it smells much better than ABS juice.

It would be nice to have one of those new nozzles. How do you communicate with Steven, I am not familiar with the organization at seemecnc?

Hi, I have drilled a 3 mm hole vertically through the hotend, in the area where the heatings resistors are NOT placed. Then I filled the hole with the grey filler normally used to repair exhaust pipes. The wires are soldered to the thermistor and covered with scrimp tube all the way to the head. The ...

Thanks for your answers.

I got the old type, then. So both tubes go down the nozzle then.

/Poul

Hi, How far down in the nozzle head does the 2 tubes go? All the way or should there be space a reservoir of filament in the nozzle head? I have now had 3 incidents where the inner tube get smaller and squeze the filament. Do you think that this can happen when the printer are doing many ...

Thanks for your advices, I will give them a try.

Hi Now I have problems with Kisslicer. When I load a model, some orange tracks are shown on the model. After slicing there are some tracks sticking out of the model. These tracks are also visible in Repetier and on the print. Several items I have downloaded from Thingsinverse has this problem. Pls ...

Finally something came out of the Rostock that looks like expected. Nearly.
I have sliced it with Kissslicer.
Which parameter should I adjust to avoid the holes around the center?
/ Poul

Can I use these setting to adjust the level instead of the 3 screws at the end stops? /Poul It's my understanding that yes that works and it's how the auto bed leveling works from the LCD controller. Having said that I haven't tried it and I haven't looked at the source code in enough details to ...

thanks, however I have switched the eeprom funktion off for the moment. it is more convenient.
/poul

ok, I will revert when tested.

A question for the Repetier software (works great): Configuration.h // maximum positions in mm - only fixed numbers! // For delta robot Z_MAX_LENGTH is maximum travel of the towers and should be set to the distance between the hotend // and the platform when the printer is at its home position ...

Thanks for the files for Repetier.
FYI I had to invert the direction for all 3 drives when I switched from the Marlin to your setup.

Above it is written that the values in the configuration or eeprom can be changed from Repetier. How is
that done?

Br Poul

thanks, i look forward to try it.

/Poul

I am trying the Kisslicer now.
However there is no commands to the extruder motor.

So it prints like hell, but no filament comes out.
(My extruder is working fine when using Slic3 and within the Repetier.

Any Ideas??

Hi,

I would like to move my printing activities to a laptop pc.
However, the RAMBo_USBdriver cannot install as it apparently needs a digital certificate.

Does anyone knows a work around?

Looking great, congratulations
