Z axis has been calibrated as far as movement is concerned. Ie if i send a command to move 10 mm it will move 10mm up. Only when printing. Maybe the acceleration during printing is high causing the steppers to skip step.

X and y has already been calibrated. X y steps is at 80.4 which is very close to the theoretical 80 from just calculations. Holes are off as u said. The diameter is consistently off by 0.4mm for a 10mm hole. I thought it was normal since you told me yours was off as well.

Is there a way to input gcode commands into repetier? I like it but the lack of ability to send direct gcode command is a major downside for me. Im using pronteface for now with the cura engine as the slicer.

Thanks, its good to know!

If the Z-axis stepper motor is skipping a few steps then, the motor could be underpowered. You might have to turn up the Z-axis step stick variable resistor to increase the stepper motor power. It could also be due to the step stick over heating, so make sure it gets a heatsink and a fan to cool the electronics. Other problem could be due to the threaded rod and linear bearings that needs oiling. Other than that, make sure the rods are aligned, the misalignment can cause a jam on your Z-axis.

Yes, its normal and its good to know so next time you can factor an additional 0.4 mm in the design to compensate for inaccuracy.

As for the repetier-host, isn't the Gcode input bar that says "Gcode:" just below the "Manual Control" tab?

hehe. did not notice the gcode command area. will start switching to it!

I had underpower issues using single stepper driver. so i resorted to using two seperate driver. and the skipping is gone. also have a fan pointing towards the RAMPs board. The rods are aligned as best as i could. Still figuring it out. For now am waiting on my thermistor for the heat bed. I dont have that yet so the heatbed isnt on, large prints are peeling off. so stuck with small prints for now.

its fine. i'll update once the printer is running as good as yours

Sure, just keep us up to date.

Also on a side note, you may want to insulate or cool as much as possible the PLA parts that are holding the heater bed or near it especially from the heat because PLA tends to soften and deform from as little as 50 Deg C.

found local suply for igus bushing!

Good for you, in case you didn't know the Igus branch in Singapore couldn't be bothered with small orders. Lets see if this one does the same...

By the way, I just made a video on casting out tin-lead solder using plaster mold that was shaped by a 3D printed part. Enjoy...

if you start using it already write us a review!

can be ordered online from their website, no minimum order specific the more you buy the cheaper the price

I remember you can request for samples from their website.

Guess what, I went ahead and ordered a few samples... Lets see their response in a few days

You guys should try out their sample request too

[UPDATE]

Just got their web reply on the sample request and guess what...

ehe. what does it say on google translate?

Translation from German to English here...

Printing complete. Total hours to print is about 65 hours.

Sweet.

The shop I suggested didn't have gt2 belt and metal pulley.the pricing is also bloody expensive.I'm going to look for others today.how much are you planning to sell your gt2 belt?

how long you need feiming? I have some extra I also have some extra 20T gt2 pulley, not looking to make money just helping out fellow reprap PM me if you interested

Super nice! worth the effort!

Its all in ABS or PLA? Planning to migrate to this frame or building another one from scratch?

Well, I guess you now know how I felt about some suppliers.

I am planning to sell the GT2 belt at RM 25 per meter and it can be cut to any specific length, up to 10 meters currently. I will be frank with you, the GT2 belting is for my own maintenance and development for a new printer. The price I listed includes a reasonable margin for my service to survive and also for the development of that new printer. I may not sell that new printer I am developing but if I get enough support through my printing service, I may consider expanding into selling 3D printers. Besides, I am not really earning much to grow this business at all, just barely surviving.

Anyway, I would suggest DarkTenno since he has some reprap parts to let go and I don't stock the pulleys because I can print them.

I just check 3Dprinter.my for their pricing, they having discount... Go get the 20 meter one at http://3dprinter.my/abante/pulley-and-belt...idth-open-ended

I make 0 income from reprap as most of the time I print them because I like to see the printer printing lol, I can spend most of time in front of my printer and watch it print this thing never stop to amaze me . but occasionally I do help printing stuff for my friend with reasonable fee just to cover maybe a few extra spool of PLA

side note, order some new heat break for my mendel would take a while to get to me, hopefully it don't get stuck in Christmas backlog, haven't really try to dismantle the hotend yet been lazy these day well that also maybe due to I still have 2 working printer in hand

I was thinking i could make some money out of this,but realize there's too many people doing that and the market is too small to sustain.

you can still made money out of it if you can the correct group to market your services

altan printed in PLA, planning to start a 2nd one from scratch. Plan to take this slow .
