Germany defaulted on some of the payments and France responded to that by occupying Ruhr (https://en.wikipedia.org/wiki/Occupation_of_the_Ruhr). That took out a substantial portion of Germany's production capacity, but they were mandated to keep paying the reparations. The German state tried to keep up with that by printing money, triggering hyperinflation and paving way to the Nazi regime.
When you combine that with Germany and Prussia's lack of access to steel it meant nobody could make anything whatsoever. The impact of not being able to import steel and French occupation of the one major remaining steelworks plant in Krupp is one of the handful of reasons why Prussia was dissolved and absorbed into the greater Weimar Republic nine years later. Prussia couldn't handle the debt caused from the two years of no steel and coal at a time where the republic was so poor they were asking the English and Americans for loans they knew they couldn't repay.
You've got the dates mixed up. The era of hyperinflation and the occupation of the Ruhr occurred from 1921 to 1925, after which the "Weimar Golden years" occurred where the NSDAP were a small minority. The Great Depression occurred in 1929, which promptly crashed the German Economy. Unlike in 1921, this time the government chose austerity which caused great hardship and radicalized much into either the NSADP or KPD. The ruling centrists weren't able to govern without support of either, hence they planned to use Hitler as a "puppet" between the President and the Vice Minister. That plan backfired, although it is to note Hindenburg could have fired Hitler at any time.
Afaik, the printed money to continue paying all the wages for the workers in the occupied area, who went on strike, due to the occupation. Don't think they could pay reparations with freshly printed Reichsmark.
