It includes Full HD instructions, brief with tips and tricks, extra pictures and a pneumatic schematic. LEGO GBC 12 – 42043 I already bought it and WOW!! its awesome. Hopefully I can finish it this weekend! Quote
GBTechnic Posted January 13, 2017 Author Posted January 13, 2017 Another winning C Model/GBC build. This guy is a genius at creatively using these sets. This 42043 GBC model looks really playable, particularly the moving elements in the platform, the speed that the balls move thru the loop and the way the platform moves up and down too. I have to say though that I am no particularly happy that two C Models I really want have release dates in July 2018 (42042 Inverse belt lifter, "GBC 9" or the first 42043 GBC model. Who wants to preorder a set now that won't be seen for 18 months?! Now if preordering will move up the delivery timeline I'll do it but don't tease me with an awesome build and make me wait so long!!! ? Quote
Freezer118 Posted January 16, 2017 Posted January 16, 2017 I think the July 2018 dates are more fictional and will change to a exact release date when PV is ready to release the GBC model. (instructions ready, GBC 100% functional etc.). Same for the 42052 GBC model. Quote

IMO 42042 is the best set in last 5-6 years when it comes to design, functions, MOD-ability, playability, Cmodel-ability, fun, appearance. On top of that it is not so expensive. Seems strange that general attitude towards 42042 is like: "yeah, OK" instead of adoration it deserves. GBC model is really cool! Totally agreed. I have been constantly tinkering with and improving my 42042 Crawler Crane since I bought it. It's easily my favorite set out of many thousands of dollars of LEGO I've owned over my life. On topic: This GBC is rad. I may have to pick up another copy of this set just to build it. Edited January 16, 2017 by wmeredith Quote
MIchaelF Posted January 16, 2017 Posted January 16, 2017 Just completed this build. Very enjoyable although also somewhat challenging as some steps require partial disassembly of earlier ones, and some connections aren't clear from the diagrams. Only issue I see is the strain on the motor as the arm that flips back and forth reaches it's stops. Just waiting on the balls to arrive now! Quote

See instruction page: Ver 1.pdf: page 85 step 25 Ver 3.pdf: page 13 step 25 The plain 2L sleeve in the middle of the drive from change over unit out to turntable acts as a slipping clutch. ------------------------------------------------ I have been building this using spare parts not parts from the crawler crane. So far manage to get 3/4 of the machine working. I cannot get the ferris wheel to work, the grab arms keep fouling various other parts and is rotation is very jerky. Every time the change over driving ring shifts from one position to neutral and then other position the motor strains and imparts to a jerk to the whole drive system. With the older RED driving ring you could remove the 2L sleeve with ridges and replace it with a plain 2L sleeve which gives amuch smoother c/o. I have used this with success on two GBC lifts I have built. A plain sleeve is not possible with the GREY driving ring, tried a 2L plain sleeve with 1/2 bushes each end to get 3L length but the 1/2 bushes don't enter the end of the driving ring. It would need a complete re-design of the change over gearing & output to be able use a Red driving ring. Edited January 17, 2017 by Doug72 Quote
MIchaelF Posted January 17, 2017 Posted January 17, 2017 Ahh, the sleeve was fixed too tightly so have that fixed now. Thank you! I don't have a problem with the drive train jerking, but the claws do touch the conveyor belt and don't seem too engage the tipper axle on the ramp very well. I don't have the balls yet though so I need to see what difference the extra few grams make to the rotation. Quote

I got it working with not to much trouble. takes a little fine tuning as described in the build On their website they also have an older module (something called like stop, reverse mechanism) which is what you described i believe. Unfortunate that lego changed that.. Maybe they will bring out a new part 3L smooth in the future. Quote
MIchaelF Posted January 18, 2017 Posted January 18, 2017 (edited) Do the grab claws catch on the conveyor belt and ramp for you @Carl86? Edited January 18, 2017 by MIchaelF Quote

MIchaelF Posted January 18, 2017 Posted January 18, 2017 Thank you! I'll try it when I get the balls. Quote

MIchaelF Posted January 19, 2017 Posted January 19, 2017 Got the orange balls today from PV and have spent hours this evening trying to get it to work properly. Unfortunately I have to give it a big thumbs down The drive train is just too jerky to work properly and the claw timing mechanism is not robust enough to be consistent. The ramp down from the tipper trays also needs modification to make it work properly as the balls jam up in it. It's an interesting build but eventually a big disappointment. Quote

Funny, i got it working in one go but at my friends we got the same problem but it really helps to make sure that all the axles are not too tight and can run freelyy! I contacted the guy, gave me some usefull insights There are also some variable you can finetuen in the ball fill mechanism for the ferris wheel. Quote

Glad yourballs have arrived ! I will be ordering mine soon. Totally agree with your comments. As I am not building this solely with parts from the crawler crane I have been modifying ball runs etc. to prevent balls skipping off or jamming. see image showing ball guides between tipping arms along ramp to ferris wheel. (ferris wheel unit currently removed)IMG_4252 by Doug Ridgway, on Flickr Also to prevent the change over mechanism from imparting jerks to the drive train I have developed a C/O unit with stepless motion, and strengthened the structure whilst keeping input / output axles the same. This uses the old Red driving ring with a plain 2L sleeve for it to slide over. IMG_4253 by Doug Ridgway, on Flickr IMG_4254 by Doug Ridgway, on Flickr I have yet to install this but testing with a M motor it runs very smoothly dispite the odd linkage to the red c/o lever and without any flexing of the structure. All gears same as per original unit but configured differently. Tested with linear slipping clutch and T/T motion OK and puts no strain on the drive. Next step is to re-build the ferris wheel to see if can get this performing consitently. Edited January 20, 2017 by Doug72 Quote

I also saw in the LDD software that there is a special new 3L axle extend piece where the dark gray clutch moves over. In the 42042 it has ribbles but in the LDD software there's a extra piece wthout the ribbles. Can that be the solution? Does someone already has that piece to test? I will make a screenshot later today Quote

I will make a screenshot later today If there were such a piece would be great. Can't locate one on Brickowl - maybe someone else knows if it exists or due to be released. An alternative would be to remove the two small catches from the grey driving ring, (in the middle section) so they don't engage with the ribs on the white 3L gear shifter.

AkiyamaWataru Posted January 20, 2017 Posted January 20, 2017 It exists. The Part was released in 42056 first. You could directly order them from TLG (bricks and pieces has been taken down till first of february) Quote

Needs a 3L shifter without ribs. Do you have a part number for the plain version without ribs ? Quote
